Title: E-Body Tire Combos
Post by: Carlwalski on March 27, 2006 - 08:02:50 am

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from www.jegs.com All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries.  :thumbsup:

Cheers,
NZ440R/T

Panther Pinks Combo:

295/50 R -15 with little clearance to the leaf spring.  Fits inside the wheel wells though.

1972 Dodge Challenger
Centerline Autodrags rims and BFG T/A Radial tires.
 The fronts are 15x7's with 3-5/16" bs on 225/60/15's
 The rears are 15x8.5's with 4-7/8" bs on 295/50/15's
 ******NOTE: This is on a stock E body width 8 3/4 rearend, I HAD to use a 7/16" Mr.Gasket wheel spacers to give the tires at least 1/2" clearance from tire bulge to leafspring, because all it had was 1/16" to 3/16" clearance without them. I also installed 3" long ARP wheel studs and open end lug nuts in the back, so I'd have plenty of threads for the spacers*****
 ***So if you like this look and want to use a 8.5 wide rim just find a rim with a 4 1/2" backspace and you won't need any spacers! Yet it will look the same.
 It just barely touches the drivers side when I hit a big bump, but I'm still using stock shocks with re-arched leafsprings. If I added KYB shocks or rolled the inner lip a little or trimmed it wouldn't hit.

Just put on new tires. Car is a 71 cuda--stock 8 3/4 rear with new espo 1" over stock height springs. To fit 275/60-15 tires I had to buy new  15x8 ralleye rims(from wheels vintique)  4.5" backspace. Front tires are 235/60-15 on stock 15x7 ralleyes.

Post by: Super Blue 72 on April 24, 2006 - 09:48:43 am
Here's my info for the 14" crowd:

1972 Challenger Rallye
Stock suspension, 8 3/4" rear end
Factory Mopar 14"x6" Styled Road wheels (Magnum 500 style)

Fronts: 215/70R-14
Rears: 225/70R-14 (a little taller and wider)

For the 14"x6" rim, from what I saw, the widest tire you can "safely" mount is a 225/70R-14 or a 235/60R-14 tire.
There's also a pic comparing the 2 sizes.

The way I did it (If I did it right!  :banghead:) is you can take a straight edge/ruler/rigid tape measure and lay it across the diameter of the rim on the lip then measure down from the straight edge/ruler/rigid tape measure to the mounting surface of the wheel.

Sorry to stumble on to this late, but did the springs have to be moved inward to fit these tires? Any more than 4 inch backspace or so, will give you trouble in an E-Body. You might get away with 4.5 inch max on a low profile tire.

MEKrunner unfournately I ordered the 255/70/15 series. Is there something wrong other than the difference from the 60 being 27 inches tall and the 70 series being 29 inches tall? I tried to order the 60 but, they were on back order for 2-3 months. Now you got me all worried.

No, no worries here, it's just that people usually put the wider tire on the rear. Your fronts are fine, and low profile, the backs will have alot of rubber. They will fit. I just don't know how it will all look.  :dunno: I don't mean to scare you.

Well to be honest I figure I would be different from the rest of the crowd. Yeah it will be a lot of rubber but, I like fatties on the back. I could of went with a 15x8 rim with 275s but, I didn't want to push it. Anyways, it will probably look a little weird but, the car will have a little rake to it. Besides that here's the current setup on the car

205/75/14s up front; with 235/60/14s out back.

From I what I can tell the front tires are taller than the back:

Boy, I hope that's not pushing it cause I just bought 15x8 Rallys with 275.60's for the rear and 15x7's with 235.60's for the front.  Waiting on center caps now.
Title: Re: E-Body Tire Combos
Post by: Prowler Orange Challenger on May 12, 2006 - 08:41:52 pm
ROMI I know some people with 295s have problems with rubbing but, I guess it depends on the wheel. Honestly, I don't think you'll have any problem with the rears or fronts. There's a guy on the Charger with a 69 General Lee Clone running 15x8s with 255/60/15s and 275/60/15s out back. He had to do a little work on the front fender but, other than that he didn't do a lot.

Post by: Hopalong on May 15, 2006 - 04:55:44 pm
Quick tire sizing lesson.  Some simple math will help to figure out the over all sizes of your tires.  First of all, the width of any modern tire is measured in millimeters.  Use this formula to convert from millimeters to inches:  Millimeters divided by 25.4 (25.4 millimeters equals 1 inch).  If your tire size reads 255/60/R15, ten your tire is approximatle 10 inches wide (at it's widest point).  255 / 25.4 = 10.03937.  The next number, 60, is a percentage of the tires width for the sidewall.  In other words, the sidewall is 60% of the tires width.  Since we know the tires width is 10 inches, we can take 60% of that to figure the height of the sidewall, approx. 6 inches.  We can also figure the overall height of the tire by doubling the sidewall height (top of the tire plus bottom of the tire) and adding the rim's diameter.  We know that the sidewall is 6 inches tall, so we multiply that by 2 to get 12 inches, then add 15 inches for the diameter of the rim to get 27 inches.  This will work for any modern tire that is described in sizes using numbers.  The old letter system is alot more confusing.  Please note that the second number in the size description is not a set size, but is a variable.  That is why a 215/70/R15 will be close to the same diameter as a 255/60/R15.  Of course all these sizes are approximates as there are variables between manufacturers.  Often times, a manufacturer can give you a good idea of all the tire sizes if you explain to them what size tires you want on what size rim.  Do the research first and save yourself alot of headaches later.

I have a 73 Cuda and I am buying my tires and Rims shortly. I am going with Centerlines. I would like something with a good amount of Meat in the rear and I would like the rear to be taller than the front.
Any recomendations would be appreciated. I do not want to modify anything. I have an 8.75 rear.
What rim width and tire size would you recommend based on a 15" wheel?
Thanks

Do you know the backspacing for the Centerline's? That would be a good start here. 4 or 4.5 inches would work best. Then you could go 15X8. You can't go wider than 8" without any modifications, unless you want a low profile tire(which you said you don't).

Post by: 73Cuda73 on May 19, 2006 - 05:15:00 pm
Thanks for the quick reply. Unfortunately, I don't see any that are 15 x 8. It looks like my only option is 15 x 8.5 for the rear and 15 x 7 for the front. Here is a chart of the info including backspacing from Centerline for the 8.5
   
15 x 8-1/2  3-5/16"  5 x 4"
15 x 8-1/2  3-5/16"  5 x 4-1/2"
15 x 8-1/2  3-5/16"  5 x 4-3/4"
15 x 8-1/2  4-7/8"   4 x 4-1/4"   
15 x 8-1/2  4-7/8"   5 x 4"
15 x 8-1/2  4-7/8"  5 x 4-1/2"
15 x 8-1/2  4-7/8"  5 x 4-3/4"

Is the bolt pattern a 5 x 4-3/4" for our Mopar E-Bodies? If so, it looks like I have 2 options for backspacing.
If I go with these 8.5", what mods or additional parts would I need to purchase? Thanks Again!
Title: Re: E-Body Tire Combos
Post by: MEK-Dangerfield on May 19, 2006 - 05:36:22 pm
Thanks for posting that chart. It helps a bunch.  :thumbsup: These cars are a 5 by 4.5 inch bolt pattern. It looks like one wheel would go too deep without modification, while the other(3-5/16" backspacing), might work with a low profile tire. Again, I know this isn't what you want, but if you put alot of rubber there, it will hit your fender on any bump. Sorry I can't help more.

 On the front of my Challenger I have 15x7's Centerlines with 3-5/16" bs on 225/60/15's that is the limit for this offset. My car is as low as I can put it without hitting the fender brace.
 I tried some 235/60/15's and they hit the low front fender when trying to turn.
 Why Centerline doesn't make some better offsets for mopars I don't know  :dunno:

I keep them tight because I have the feel for it and as it looks bad Unfournately, I don't have any access to any air tools nearby and I don't make a ton of money at this point just yet. Call me a redneck mechanic but, sometimes you have to use what you have and I don't have a lot of the shops around here that I can trust to do the work being around a military base.
As for the front end I thought the same thing and that problem will be getting fixed. I bought the car like that. I'm young and I'm still learning on these cars.

for 17's

I'm running weld EVO's 17x8 front and 17x9.5 rear on my car with 245/45R17's front and 305/45R17's rear. The front wheels are 5.7" backspace and  the rear is 5.9", Super Stock springs with 1" offset hangers, 3" (yikes!) lowering blocks, longer studs and 3/4" inch wheel spacers (rear only). The rear outer wheel well lips were cut (would be better to roll them). Would have liked to have a different offset, but choices were limited when I bought the wheels. I have a set of ET Streets for the track, 28x11.5 on 15x8 centerlines with 4.5" back spacing, no spacers. Last pic is a 275/40/17 on another 17x9 with 5.9" offset, I think it looks small but that is just me.

Man Swedish, that is not good.  :eek7: :sly:
One decent bump and your quarter panel is in the crap.

I would definitely look at getting a better BS wheel combo. 4-1/2" works well with those tire sizes. Maybe a relocation kit but you definitely need to do something.....I wouldn't even drive the car with it sitting on the tires like that.

Do you guys think this combo will work on a 73 challenger?

American Racing Torq-Thrust wheels 15 x 8.5.

The tires are Goodyear Eagle GTII fronts are 235/60-15 and rears are 275/60-15. In looking at the web site it appears the offset is -24 with a 3 3/4 BS.

It seems a little tight on the outside rear fender.

These are used and I should be able to make a good deal on them.   Please let me know your thoughts.

I am about 98% done with the restoration. Go the 440 installed, and now working on the tires and wheels.

I can tell you from experience that the rears won't even come close. I never tried the front because the back was so far off. You need at least 4.5" backspacing to get those tires inside the quarters.

Rims are Coddington JYD.
Fronts are 18x8 w/4.25 BS...tires are 244/45-18
Rear is 20x10 w/6.0 BS...tires are 285/30-20. On the inside, there is 1/4th inch of room between the wheel and leaf spring.  The outside lip has 1/2 distance between it and the wheel.  This car is will be lowered about 1 3/4" this winter.

Here's another with 17" Coddington Smoothie II's
Front: 17x8 w/4.25 BS and 245/45-17 rubber
Rear: 17x10 w/6.0 BS and 275/40-17 rubber...lots of room to spare-1/4" on inside, over 1/2" clearance on the outside.  The shorter tire would also allow for a lower drop as there is more distance from the wheel to fender well.

Post by: Troy on September 15, 2006 - 01:01:00 pm
I think the springs would have to be relocated for a 6" BS. I know DoctorDiff's 1" relocation kit will allow a 10" wide rim with 6" BS on a stock e-body rear (move the spring perches) OR a 10" wide rim with 5.5" BS using a b-body rear (stock spring perch location). A tire with zero protruding sidewall just might fit but my car only has 6 1/8" of total space from the hub face to the spring on one side. A 1" relocation would give me plenty of room for 6" BS.

I actualy read all the diff posts on tire combos. Did a bunch of measuring and this is what I bought. 17x8 with 4.5 for the front with 245/45. For the rear I did 17x10 with a 6.25 back space. with  275/40's. Right now this is on a stock 8 3/4" rear with factory spring location, lowered almost 2 inches. I bought them knowing they should hit the spring. With the goal being 3/4" relocation in the future and bigger tires at that point. They did bump the rear springs so I have a 3/8" spacer and longer studs. now I have just shy of 1/4" inner clearance and almost 1/2" out side. VERY TIGHT but no rubs after 500 miles. the fronts however also sit 1/2" from the fender lip and because it's low will rub going into driveways if you dont go SLOW. The rims are Coddington Junk yard dog's Hope this helps -Bob

Is it only the driver's rear that's a problem?  Not the passenger side?  :clueless: 

If so, I would take some measurements as the quarter panel replacement may have something to do with it.  In theory, there should be some symetry between sides to some extent. 

It seems that people are getting away with 275/60-15s without any modifications.  :dunno:

 :working: I wasn't aware of that.  I have to reflect on that issue a bit.  I may pay the body shop to shave that a little so I can fit a wider tire in the well.  Of course my drivers side quarter panel had to be replaced last year and he mentioned he had to do a little shifting to make my tire fit properly in the well.  Perhaps he corrected the problem for me and I'll be able to fit larger tires in the wells.  I'll find out next summer since the rear tires have less tread than the front.  I've been a little heavy footed over the past year  :burnout:

 Poor car looks ridiculous (kinda like that cuda low rider that super blue thinks is the shizzle above { :lol2: kidding....}) with the keystones and 215/60/14 tires I bought it with. I hung a set of 275s off a truck of my dad's on there once and it looked like it would run a 10.46 at 120, so I said screw the 255s I was thinkin on, I'm goin all the way! the 2 yr. wait was worth it even if I needa make some adjustments for a better fit, they look soooooooo sweet  :droolingbounce:

You have the same car/tire/rearend combo as me.

I went w/ a weld prostar 15x10 w/ 5.5" bs and I am too close to the leaf spring.
I went w/ a 1.5" offset shackle and it's still close.

I may go back to the E-Body rear, which'll move me out 3/4", I can go back to the 3/4 offset shackle.

I rolled the fender lips when I replaced the lower quater panels. I should be just right.

Alrighty i guess Ill add my combo to the archive. Well the rears atleast.

Okay; Wheel Size: 18" x 9", 5.9" Backspacing American Racing wheels.
         Tire Size: 295/45/ZR18 Nitto 555's -11.6" Patch - 28.5" tall (Which was my big concern, see too many 'big wheels' going on muscle cars with short 25" tall tires that look goofy to me. Also with 3.91s in my rear, I needed my tire height. Tires aren't cheap, but dang they look good.  :grinyes:)

Current Car Modifications - My 1/4 panels are lightly, lightly rolled from my previous wheel combonation. There is a chance it will fit a bone stock   1/4. I am running Super Stock leaf springs, again not needed. I could lower my car back down if I choose to with no ill effects. I am adding longer Mr. Gasket studs, and will need to run a 7/16ths spacer to keep my tire off my leaves. Combo fits 100% in the wells, looks like rubbing will be definately non-existant.



More pics will come as soon as my studs get here. Anyone interested, please feel free to PM or email me with any measurement questions, more detailed pictures, etc. More than happy to help.

oh and I LOVE THE LOOK  :drool:

With my past testing, a 9" wheel should only have a 5-1/4 max backspacing.


Yup and with 295s and the rim i want coming in 4.5, or 5.9" backspacing. I'll need 7/16ths worth of spacer, and am adding longer studs. :wave: I wish for a decent cost perfect wheels could be custom taylored, id be on the roadddd  :working: :burnout:

Mike,
You know that if you move your spring in an inch like I did that you can use a 10" wheel like mine.  Then you can dump that spacer.  I even made a modified sway bar mount that uses a second hole for the relocated leafsprings. Look at Dr. Diff's kit or make a set like I did.

Thought about that before hand. No welder, no real reason to move the springs in, they fit in the wells just fine. To be honest i dont think i could afford a bigger tire!  :lol:
Title: Re: E-Body Tire Combos
Post by: Troy on August 19, 2007 - 09:33:46 pm
Dr Diff's spring relocation kit doesn't require any welding. It's designed to use the skinnier b-body rear end (which would only be a problem if you don't have access to one). You would have to reweld the perches on an e-body rear if you keep it but this allows you to use a 10" wide rim with 6" BS - which gives a broader range of after market wheels in the larger diameters (17" for instance). I happen to have a few extra b-body 8 3/4 rears but I'm disappointed so far with my wheel search. :(

By the way, are those Torque Thrust 'M' wheels? I've been checking them out and they come in lots of handy sizes.

I happen to have a few extra b-body 8 3/4 rears but I'm disappointed so far with my wheel search. :(

By the way, are those Torque Thrust 'M' wheels? I've been checking them out and they come in lots of handy sizes.

Yep, no spare B-body 8 3/4 hangin around  :eek4:. I'm okay with 6" BS and 9" wheels on my stock setup with a little spacin. Yep Torq thrust M's :cheers:

Or use a wider rear end out of another car. I think the 71-74 B bodies are 2" wider. Station wagons and C bodies are 4" wider.

I suprised that more guys who are using later model style rims with lots of backspace don't just swap rear ends. Its alot easier than cutting and welding.
Title: Re: E-Body Tire Combos
Post by: Troy on August 20, 2007 - 02:19:06 pm
But you have to weld the spring perches to use a wider rear end right? Or are the frame rails the same distance apart as an e-body? The 68-70 b-body rear is a bolt-in if using Dr Diff's hangars. This is great because then it allows a common size for 15" wheels (10" with 5.5" BS). Using a 15" wheel is probably much more popular than using the larger diameter wheels. If the other rears are bolt in then it's definitely something I'll be looking into.

I see absolutely no reason to dump a few hundred on another rear. And have another rear laying around instead of just running a small spacer in my situation. Really....295 series tires are just fine with me on a stock setup  :dunno:

Post by: HP2 on August 20, 2007 - 04:43:12 pm
Yes, spring seats would need to be welded on to match what ever body style you are putting them into. However, it is a heck of a lot easier to take a housing to a shop to have it welded than it is to take a car in. Plus, some folks may want the newer rims without altering the car itself.

The Dr Diff kit is great. There are a plethora of spacers out there that are not bad either. I'm just saying there is another way to do this type of change over that, depending on where you live, could be a lot easier or cheaper. In my neighborhood a C body rear end can be found for $50-75. That is cheaper than a high quality, billet spacer and in the same range as some of the Dr Diff stuff.

I'm just trying to point out options that others may not have thought of.

The wheels are Wheel Vintiques billet Magnums. I tried to buy a set of the cheaper American Racing AR500's but they still aren't shipping any and when I called them they said it will be sometime next year before they do. I'm not that patient.

No, they will not fit. I couldn't even get the 275s into the wheel well of my Barracuda on a rim with 3 3/4" BS. Here's the car with 255/60-15s 3 3/4" BS - I already owned the wheels but these are only temporary. They fit but rub on the wheel lip every time I hit any kind of bump.

It will rub on the outside.   Then the only way to fix it will be to jack it up sky high like a '70s clown car.  You need a 4.5" backspacing like everyone else uses for the 8" wheel.

You could put in a b-body rear end and move the springs in, but then you would be able to go with a 10" wheel.

Funny you mention the B-Body because that is what they were originally bought for, and they rubbed on that, too (66 Satellite).  They were the exact size wheel/tire combo I'm looking for, but I was afraid I needed the 4.5" BS.  Not what I wanted to hear but thanks for the info, that was what I was afraid of.  :(

I have a 73 Cuda and I am buying my tires and Rims shortly. I am going with Centerlines. I would like something with a good amount of Meat in the rear and I would like the rear to be taller than the front.
Any recomendations would be appreciated. I do not want to modify anything. I have an 8.75 rear.
What rim width and tire size would you recommend based on a 15" wheel?
Thanks

I have almost the same request, except that i got a 70 Challenger instead. Also with 8 3/4 rear and i want to install AR torq Thrust with as much rubber, as i can get in there without troubles or modifications.

From what i read i guess 275 rear and 235 front would be a good setup. Also the rear should be a bit taller, to add an aggresive stance.

I'm also planning to get the XV level I suspension kit. And i absolutely don't want any wheel to rub on the well. Is the above mentioned setup safe?

What exact tire and rim dimensions should i look for?

Thanks,
Ralph

That's the easiest fitting combo around; 15x8 with 4.25 to 4.5 rear spacing. 235/60x15 is about 26" tall, 275/60x15 is about 28". Mild rake, fills the wells nicely, wont' rub, readily available.

Just put these new wheels and tires on last week:

Front: 17X8
         4.75 backspace
         235/45 BFG's

Back:  17X9.5
         5.5 backspace
         255/50 BFG's

Hey Axelrod, I really like the look of those billet magnums and I'm looking at going with a set of those same rims.  Would you still go with the 4.75" BS on the front if you could do it over again instead of the stock 4.5?  It looks like you have plenty of clearance on the front to push them out a bit.....   

I was thinking of using 17x8s with stock 4.5" BS and with 235 and 255/50/17 BFG KDWS.  Those would end up with nearly the exact same dimensions that my current 15x8 magnums with 235 and 255/60/15 BFG TA's have. 

What was the advantage to going with different BS?  What kind of clearance do you have front and rear?

Thanks,
Chris

On the car as it sits now the extra 1/4 inch BS isn't doing anything for me. I have plenty of room in the front. The reason I ordered the extra BS was in anticipation of lowering it some in the front. I put 2 inch drop spindles on my 68 Charger which has 17X8 with 4.5 BS and 245/45 on it and they rub sometimes even after taking off the wheel trim. My thinking was I can always add some spacers but you can't add BS. The wheel is just more versatile to me with the extra BS.

In the back I've got plenty of room using Mopar's XHD leaf springs. Since I posted the pictures I've lowered the back 1.5 inches or so using AR Engineering front spring hangers. I haven't had a chance to load the car up with folks and go cruising but I don't anticipate any problems. One thing I'd like to mention is I've compared the 255/50 BFG's to some other brand tires and these things appear much wider than you'd expect. They are defineatly wider than a set of 255/50 16 Kumo's that I have and they are real close in width to a old set of 275/60 15 FireHawks that I took off my Charger. So my advice is don't assume that all tires of the same stated size will be equivalent.

Post by: PlumCrazyChris on January 19, 2008 - 11:27:34 pm
Good info, thanks Axelrod.  Do you think 5.5" BS in the rear is mandatory?  Would 4.5" work?  Yours looks pretty tight and doesn't look like it could be pushed out another inch. 

According to the BFG website, the 255/60/15 TA's that I have, have nearly identical section width and .3" shorter than the 255/50/17 g-force TA's.   So I was thinking that the 17 GFTAs on 17x8 with 4.5" bs would occupy the same space as the 15x8 with 4.5" bs that I have on there now....   any thoughts? 

I have had 17x8s with 5.5s on it, but they had a smaller tire, so I can't compare apples to apples.  The 5.5s had no problems fitting, like yours don't, but I want to make sure that the 4.5s would fit, because that is the size I might get (buying from an individual). 

Also, I'm told you need a special type of upper ball joint that is lower profile for 17" rims to clear.  Is that true and can anyone tell me what brand/part # they are?

Axelrod, what type of seats do you have in your Cuda (which looks really nice)?  They don't look quite stock.

Thanks again.

It depends. If you have the bulged ones, yes. If you have the flat ones, no. Now, if you have a big grease zerk sticking out the top of either ball joint, you might have to remove it. Honestly, I've never received a bulged ball joint when I've purchased them, so maybe they are just older versions.

I think you will be plenty safe with 4.5 BS on a 17x8 inch rim. I don't have special ball joints either. I think I got the rebuild kit from PST. The seats I have are made by Corbeau. They look good but they are much to firm for me and everyone that has riden with me has complained. I have a set of Procars in another car and they are way more comfortable.

The 275/50's should be about 3/4 inch taller and wider. I think as long as your ride height isn't too low you could run them. As always a lot depends on how much weight you have in the back seat at any given time also. I don't think you'd have any problems running a 235/50 in the front. By the way, I used that Percy wheel fitment tool to help choose what sizes to go with. Here's a couple more pictures since I lowered it in the back.

I can tell you, that with the big wheels, a nice tall tire with a good patch looks awesome. Unless your 'bagged' like my dads car then the rubber bands are more in place


...Did you say 285/40 fronts? Holy moly, ive seen another member fit 275s, i think barrrely.  He is running short like 25.5" - 26" tall tires. You are looking at 27" tall with the 285/40/18s. My front wheels are 4.5" backspacing, 27" tall, 235/50/17s, any lower on my suspension i will smack the center of my arch on the front fenders. I think you will need a shorter tire up front to clear

No leaf springs.

No strut rods in the front suspension either.

They also use a rack and pinion steering set up, which I've heard has reduced wheel angle, so that helps reduce the prospect of scrubbing the wheel sidewalls inside the fenders.

Title: Re: E-Body Tire Combos
Post by: HP2 on February 22, 2008 - 03:44:32 pm
That would make sense for a stock suspension, although that is a tad small for the rear. I personally think you can go woder than that, even with leafs int eh stock location, but wheel choice becomes critical.

They have put 275 front and 335 rear using the Level 2 system under a Challenger. Not sure of the wheel size they are using, but it is in here somewhere. You can search for it by looking for posts from dqhemi.

Bump steer on their rack system is minimal. Since it is a completely fabricated system with relocated pick up points, they wouldn't have the same interference issue as a rack retrofited to a stock suspension.

When i was sizing tires i believe the magic number was ~1/2" IF you are going with a thin sidewall tire. Going big tires on 15s and big tires on 18s is a different story on sidewall flex and clearances.

Are you set on 18" rims?

With stock suspension, if you run 17x9 with 5.5" backspacing rim in the front you can run a 275/40/17 tire up there. You need to have the flat type upper ball joints though.

See this site for 17" rim fitment: http://www.moparfins.com/CLAIRDAVIS/1969_front_end.htm

Here's a 68 Barracuda with 17x9 and 275/40/17 tires. If he can fit it on an A-body Barracuda, you can with your challenger. He had to cut/roll a ~3/4" by 3" triangle from the bottom front fender lip. www.conemangler.com (http://www.conemangler.com/car-wheel-r.JPG)

The 68 Valiant pictured here runs 17x9 and 275/40/17's also http://www.mrmopar.com/SpringFling2007/WillowSprings/  (http://www.mrmopar.com/SpringFling2007/WillowSprings/800/2007-05-03_035.jpg)

I did a Stainless Steel Brake Co. conversion on my front drums, and since then my wheels have dragged on the calipers.  They were some 15x7 aluminum mags with approx 4" of BS.  I have a set of Magnum 500's that do not rub, but they are 14x7 and the rubber is shot.
What would cause the 15" rims to rub the calipers, when my other wheels do not?  They have approximately the same backspace...
What wheel combo's has snyone used with success out there after a conversion to disc brakes?  I'm ready to invest in a nice set of 16" or bigger rims, but do not want to shell out the money only to find that they will eventually wear holes in my brakes!!

Well, if they are an older set of mags,it is possible that they are drum brake wheels. Many moons ago before discs became standard on many cars, wheel manufacturers offered disc and drum wheels. It is possible to have identical back space, but a drum wheel will will have flatter spokes whereas a disc wheel will have some arch to it to avoid caliper interference.

Here's some pix of my Chally.  I'm in the process of changing some things, but nothing too drastic regarding the overall look.  However, I'm definitely changing the wheels and tires.  I'm thinking of going with with either 17" or 18" wheels.  Currently (from the previous owner) the wheels are 15" Weld Prostars (10" rear and 8" front).  Rear tires are BFG Drag Radials 315/60-15 (I think that's a 30" tall tire).  I'd like to go down in size by about 1 to 2 inches 'cause it's just too close to the wheel opening at the front side of the tire (about half an inch to an inch).  I can easily fit a 12" wide wheel (and tire set-up) in the back as the previous owner did a fantastic job of a 3" mini-tub with a leaf-spring relocation and going with an A-body 8.75 rear-end housing.  My problem has been finding a 17x12 or 18x12 that I like and a 28" or 29" tall radial tire that will fit the wheel width nicely without looking too much like rubber bands or balloons.  I'd certainly be open to the idea of staying with 15" diameter wheels as long as they're retro, muscle car looking and I can get them in 12" width, AND I can find a good looking tire.  I'd appreciate some help with wheel/tire options for my project too.  My preference in wheels is the Magnum 500s like those offered from Wheel Vintiques (billet and steel) and from American Racing.  Thanks

I have a friend that just had a set of 15x12 magnum 500s made up for his Roadrunner. One of the popular wheel companies did it an had to weld up a 12" width wheel, because nobody made one in steel. It cost him a total of $1200 for 2 wheels! He also had some problems with their workmanship.

Good Luck!

Shouldn't be a problem.  If you have a 70 ebody it might be tight on the drivers side if you've had work on the rear quarter panel.  Sometimes they don't repair the quarter quite right.  That happened with my car.  Most people put a 225 on front and up to 275 on the rear.  Some people have that size all the way around.  Its your call.

Post by: GoodysGotaCuda on July 05, 2008 - 10:13:13 am
You did change your ball joints right, if not, you do realize what can happen? Ball joints causing bad camber wear is a REALLY bad ball joint.. As far as 16", make sure you shop tire sizes before you buy any 16" wheels. I think you will find more wide/tall 15 and 17 inch wheels than you will 16...just keep your options open.

I was just wondering what you guys think the backspaceing should be. I would like not to have to do any modifications if i dont have to.

Stock BS is 4.5" front and rear.  You can go as far as 5.5 on the rear with 255/60/15, but stay with stock on the front. 

A really great look, is the magnum 500s with BFG TAs.  I had them on my convertible and put them on my coupe for a while.  15x8s  with 255/60/15 on the back look great, but stick with 15x7s on the front, I had 235/60s on the front and with 8" rims I had trouble lowering it as much as I wanted.  No problem with the 7" rims, you can actually put 245/60s on it with the stock 6.5" or 7" wide rims.   IMHO, 245/60s are too narrow for the rear and 225s are too narrow for the front, the 255 and 235/245 look good on it. 

The Magnum 500s  are $139 each at Summit, Center caps are $37.12 at Wheel Vintiques, Cap retainers were $12.39 each at WV and $7.38 at Summit I think.    With a set of 235 and 255/60/15 BFG TA tires, the total came to $1,220, mounted and balanced at a local shop.   

If you can get some huge spacers, you can run Cheap 17" mustang wheels on it.  They'll fit the rear, but will need at least an 1" spacer in the front. 

I've personally gone back and forth on the subject of big rims (17-20") vs. staying with 15".   As far as I could find, you can't get raised white letter tires for anything bigger than a 15" rim.   I like them on these cars, they just look right. 

I thought I'd just step up to 17", but to get the same size wheel I have now (28" in rear) and fill up the wheelwell, you still end up with a 50 series tire and can't get RWL.   It just doen't look right to me having that wide blackwall tire.   

I think that if your going to go to anything bigger then a 15, you really need to step up to a 18 in front and 20 in rear to make it look right and have low profile tires.   A lot of guys are going with 18s and 17s, but unless you slam it and limit where you drive, it still does't fill the wheelwells very good.  My buddy Brent just got his car out of the shop and has 18s and 20s, and it looks just right at the stock ride height and no rubbing.  He has a thread on Member Restoration Projects with his tire/rim specs and lots of pictures if your interested, look under EvilTwinATX.

Good luck, let us know what you end up with.

Test fit a different combo under the car recently, thought I'd pass along the info.

295/65x15 BFG Drag Radial on a 15x8 Cragar Dragstar with 4.5 backspace. Car has zero arch springs in the stock location, so it sits a bit lower than most.

Nice rake, pro street lite kind of look.
Title: Re: E-Body Tire Combos
Post by: HP2 on August 06, 2008 - 10:49:22 pm
Dimensional specs for this combo are 29" diameter, 12" section width, 10" tread width. Fit is plenty tight everywhere, but fits. I've got about 3/8" to the fender lip without a rolled edge. I've got a 1/4" from the sidewall to the rear segment of the leaf spring. A 4.25 backspace might fit a bit better with a rolled lip, or a 1/8" space with a 4.5 backspace.

Title: Re: E-Body Tire Combos
Post by: Roppa440 on August 12, 2008 - 07:40:04 am

I tried 295/50/15s on 15x8 inch wheels with 4.5 backspace on the rear of my 1970 Challenger R/T.

I found the tyre was dangerously close to the leaf spring. Only about a quarter inch clearance.
I also think that a radial tyre that wide on an 8-inch wheel is too much. Radial sidewalls are designed to work in a vertical plane.

The whole thing looked pretty silly to me so moved the springs in on offset hangers and fitted the tyres on 15x10 wheels with 5.5-inch backspace instead.

Much better! :thumbsup:

I fitted the 15x8s to the front with 245/60/15s. These work out the same diameter as the rear tyres.

Hey guys.  I'm getting ready to buy a set of American Racing TTII wheels, 17x7, 4" BS front, and 17x8, 4.5" BS on the rear.  First of all, is the backspacing I put correct?  This is what the seller told me, but I just want to make sure.  The problem is I am undecided on the tires.  I was thinking 235/60-17 front and 255/60-17 rear, but I have not seen anything on here with the 60 sidewalls.  Would this be too much sidewall for the tire sizes I am looking at?  If so, then I would probably drop down to 50 sidewalls.  I like the look of a lot of sidewall, but also want to go with the 17" wheels.  I just don't want to end up with balloon looking tires if the sidewall is too tall.

60 series tires on 17" rims will definately be too tall.   50's will fit very well.  45's will also be good, but slightly lower profile.  Go to the Tire Rack website or here, http://www.rims-n-tires.com to see what tires will fit best.   

Typically, 235/60/15 and 275/60/15 are the biggest best fit on a factory 15x7" rim.   Factory backspacing is 4.5" 

Look for something that will fill the same space as the sizes I've shown above and you'll do fine with those rims.  With that 4" BS on the front, you may have to go to a thinner front tire, as that rim will stick out .5" more then a factory rim. 

Good luck,
Chris

Well all the studying / measuring and racking my brain FINALLY paid off for me today as it worked out just as I hoped...

The Tire - Mickey Thompson 29" tall and the tire comes in at a enormous 13 5/8 Section width and 11+ tread width..,

A real thin wheel spacer would move it off the spring some and still have plenty of clearance to the outer wheelwell lip...

its 3/8ths from the spring now and the rule of thumb is about 1/2 on either side...



What wheel width and backspace have you got there?

Post by: GoodysGotaCuda on December 16, 2008 - 09:18:51 am
Still looks pretty close there stroker! With sidewall and body movement, I hope they don't hit. How much air is in those things vs what you'll run at the track?

its hard to tell in the pic but there is more room there than it looks... a 1/4" wheelspacer will give me over 1/2"+ on each side..... the 325/50's or 315/60's is 1/4" less width than these tires also...  :working:

Okay, I'm looking for what will hopefully be a quick answer.  I am looking to buy a set of American Racing TTII wheels for my Challenger (stock suspension).  I want to get 17x7 on the front, but I have only been able to find a 4" backspace for that wheel and size.  Will that work, or do I need to get a custom backspace of 4.5"?  Tires will either be 235/50-17 or 235/60-17, just not sure of the sidewall height I want to go with.  Would this play a factor in the backspacing I need to get?  Thanks.

Here's Dr.Diff's E-Body 1" offset hangar kit; using a motorcycle jack to install a 1968 B-body 8 3/4" housing. I also snagged the lightened spool from him ($85) on Ebay. Now, the 275-60-15 (10.5" Section width) Kelly radials leave  1.3" room @ the leaf. The Hoosier Drag (29x10x15") slicks on 8"x15"Weld with 4.5" back space, are 11.9" wide and will leave .6" room @ the rear leaf. But once you let the car's weight onto the slicks they fatten to leave only .3" to .5", so the passenger side needed the 5/16" spacer. This loaded carrier is 60 Lbs., stock housing is 40#, the axles are 20# each with 3" Mopar Perf. studs, total 140#s plus the brakes. Moser's housing's 60# bare. I went for less weight on this one, with the 741/ 3.91 ratio. Front tires are 215-70-14" on old 6"slots for now.

Not without spacers... From everything I'm looking at 5.5/5.6" of backspace is tops for a stock rear, probably a little less (~5") in the front, especially for a 9.5, probably less even in the front...

At this point I would say the car is finally done.  I just got the new wheels/tires mounted as a belated Christmas present.  The wheels are AR Torque Thrust II, 17x7 front and 17x8 rear.  The tires are 235/45-17 front, 255/45-17 rear.

They look great 73,  plenty of clearance there.  Now you can drop the car 2" or so and really dial in the handling.

TT2s are such a classic look, hard to go wrong with those.

Quick question for everyone.  How much room do you need for clearance to the 1/4 panel lip and also the leaf spring?  I was thinking like 1/4 inch each?  Does that seem about right?

Title: Re: E-Body Tire Combos
Post by: 72bluNblu on February 27, 2009 - 12:33:38 pm
a 1/4" is pretty tight. Somewhere between 3/8" to 1/2" is probably a better bet if you want to avoid rubbing, keep in mind your tire profile changes under certain driving loads, and the suspension can move a little in relation to the body during cornering.

:iagree: on the quarter panel side.  I would think the leaf spring side could be run down to a 1/4" or so.  I don't think the side wall is going to flex a 1/4th of the way around the tire from the contact patch to cause an issue on the inside.

Depends on the sidewall height.  If they are 15" wheels with 60 or 70 sidewalls, then they could flex that much in a hard turn, but under normal driving, probably not a problem.

Post by: Aracer on March 16, 2009 - 02:59:08 am
Check out these 29"x 10" slicks, on Weld 15"x 8" with 4" back space. There's room for taller ones too, provided you use SS springs instead of the 440-6 pack pair shown here. That third spring clamp on the driver's side had to be removed for clearance . Removal, helps limber the leafs for "rise".
     The slicks and wheels are 40# each, and the springs are 35#each , so 150# plus the 140# for the loaded housing and the brakes @ 50# for a total of 340# "un-sprung weight".  :bricks1:

I run mine about a 1/4" (45 series tire) on the leaf spring side and they don't rub. I would also agree that a taller 60 or 70 series tire might need more side clearance.

Post by: EvilTwinATX on May 01, 2009 - 01:45:57 pm
I believe the Rear BS was 5.5 and the front was 5. Of course, you must have wheels that will clear the upper control arm too - I think this requires at least a 17'' wheel.
you also might take into accont if you are doing a big brake and if that will adjust your spacing out or not..

I must have measured 50 times!

Word of caution: If you order the wheels with a little too much backspacing you can shim it out a 1/4 inch without issue - but if your backspacing not enough there is little you can do to fix it.

I can look through my papers and find exact specs if you give me a bit.

Reason I am considering them is because the 14" tires on there now are trash and I'd like to upgrade to 16-18" wheels.  I have a practically new set of 225x60x16's in my gargage from a previous vehicle.

So I'm thinking that if they fit, buy the wheels and use what I've got...

If so I would advise against it and get the wheels and tires that your heart really wants.
16" tires are getting really hard to get in the sizes we need for our cars, 15" still look cool if you pick the right size rubber and 17"s and up can go ugly looking real fast if you don't pay attention to your side wall sizing.

I'm assuming your car is an Abody since you couldn't find an 8.75" rear. 

If you need 3.5" backspacing, your gonna need a custom rim I'd bet.  Buy why don't just go wider and take advantage of that narrower rear?  You can move your springs 1" inward each side with a Dr Diff kit for $150, (probably should have thought of that before you welded on the new perches...) and use a wider rim, or you can just get your rims widened, there's several places that do that.

Good luck

I am leaning towards 17's with HPO+1's on a ebody convertible.  Can you elaborate on the side wall sizing concerns.

I am looking at Crager SS 17x8 with 4.5 BS.  Going to run 245/40 on front and 265/40 on rear.  Is the rims wide enough and will these fit without rubbing.  Also I currently have 16 rims on the car with 225/60 on the front and 295/50 on the rear.  The car sits pretty high, but it has coil over springs on the rear.   But the leaf springs are old and used to be a 318 car.  The front end has been rebuilt with Poly bushings and new torision bars.  I can crawl under the car and change oil.  I know the tires I am looking at are 1" smaller in diameter.  Shouldn't that equal out to 1/2" actual lowering the car.  Would 275/40 fit on these rims that are 8" wide or would a 9" rim be better.  The cragers SS don't come in 9" widths. :banghead: :banghead:
Title: Re: E-Body Tire Combos
Post by: 72bluNblu on June 30, 2009 - 02:46:47 am
275/40's will fit on an 8" rim, but according to most tires specs an 8" rim is too narrow for that tire. You'll need to run 5" backspace to make a 9" rim work, if not a little more. 5.5" is probably too much backspace though. It has worked for some and not for others (ah factory tolerances!). A 245/40/17 is going to be way short. If your car is too high with the new torsion bars you need to adjust your torsion bar adjusters, not buy shorter tires. 265/40/17's are not exactly a popular size, there are few choices but not a ton. And that's still only a 25.4" tall tire.

What size torsion bars are you running? If they're less than 1", you shouldn't have any problems lowering the nose of the car with the torsion bar adjustment. You'll need an alignment afterwards, but it won't hurt anything else.

On a set of 17x8's your best bet are probably 245/45/17's or 255/45/17's. A 245/45 is 25.7" tall (decent for the front), a 255/45 is 26" tall. Still fairly short for these cars in the rear, but 50 series are harder to find in that width. 275's will physically fit, and I know Mike Tyler is running them on 8" rims, but as I mentioned the manufacturer specs will ask for a 9" rim for that width, you can make your own call on that one. 
Title: Re: E-Body Tire Combos
Post by: PlumCrazyChris on June 30, 2009 - 07:49:58 am
Well said, I totally agree with that, 40s are too short a tire on 17' rims.  Can you get the same rim in 18" for the same price?  If you want to run 40s, I woundn't go smaller then that, and even thats short. 

Your looking for something around 27" for the front, and 28" tall for the rear.   Stick with that and you'll be good.  Look at previous posts in this thread and you'll see a good link to a comparison website.   Plug in some known good sizes, and then it will tell you other sizes that will occupy the same space.

Good luck and please report back after your done.

Thanks alot for the advice.  I have already read all 16 pages of the tire section.  This has been more work than I ever thought.  Of course back in the 70's you didn't have many choices.  It was much easier in the old days.  I remember having 14" rims and the muffler kept getting knocked off.  Of course when I was 18 a little extra noise wasn't much of a issue.  Would like to hear the music now.  When I get the tires and rims I'll post some pics.  Thanks.

Dr.Diff's 1" offset hangar set with a 68 Satellite housing will buy you more room, but they fit with out. Slicks are 12" section width instead of 11" for the 275x60-15" so I needed more room. Add leafs to yours for more height. :thinkerg:

Front and rear are Goodyear RS-A sport sedan/light truck tires.  The best part is I have 3.91 gears, and I run under 3000 RPM on the highway with a 4 speed.

This shot is with the old exhaust system, but at the same ride height my hooker super comps are about 3 1/2" off the ground, I have to get a low profile floor jack as my standard barely fits under the K member. Based on how your photo looks, I would say your suspension settings and not the rim/tire combo is the issue, since the fender lip is still above the top of the tire. Your front tires are actually about half an inch shorter than mine, the rears are only half an inch taller, but as you can see your car sits much higher than that difference vs mine. I have 225/60/15's and 245/60/15's on mine.

You can get the front down with the torsion bar adjusters, then get an alignment (and maybe offset bushings depending on how low you go). There's lotsa threads on the suspension work needed, most of the info on my front suspension is here

Sorry it took so long, but I had to wash the car before I took any more pics.  The first three are the rear tire, and the next couple are the front tire.  Plenty of clearance with no rubbing, and I am still playing with the torsion bars and shocks to get just the right ride height.

Very nice. I have always liked the lowered look, but not too lowered. I dropped mine in the front and rear and used this car as the model. I'm unsure but I think his wheels were 17"s and the body height about 1" above the rim line. I went with MUCH fatter tires than his.  :smokin:

Do you have to roll the lips to get 275/60/15s?  I have 15x8 rims with 4.5 bs with 245/60.  I thought the 255/60 might rub.

How much clearence do you need for the 1/4 and also the leaf?

By comparison, I've got 295/50x15 on an 8" wheel with 4.75 backspace. I've got no rubbing anywhere regardless of load. 10" wheel would be another story. Even a 9" would get tight. There is a lot of variance in these cars from the factory and then figure aftermarket body work can significantly alter those dimensions and it becomes very critical to measure each side of each cor before diving in to a wheel and tire combo.

How do you guys with the 275 60 15 bfg, 15x8 with 4.5 back spacing in the rear manage to not rub. I have my new set on and i cant lower the rear too much or it will rub on the quarter.

I had that in a completely stock setup....... someone at one time must have changed the rear! same clearance on the other side...

Here is the transformation of my car!

2nd pic is a MT 28*12.5*15 on a 8.5 with 5" backspace and yes its touching the spring

My 50 series tires are 1/4" off the rear segment of the spring. Since they are a reasonably rigid sidewall, so it has never contacted. Also considering the spring passes close to the middle of the tire, there is also very little deflection in that area to cause problems.

Title: Re: E-Body Tire Combos
Post by: 72bluNblu on October 11, 2009 - 04:37:40 pm
The shorter sidewalls on the tires for the larger rims account for the handling difference. Since they're shorter they flex less, so you get a more positive feel when cornering, much more precise feeling. But since they are stiffer they transmit more of the road imperfections. Typically things don't start to get really harsh until you get down to a 40 series or below, but that's just a ballpark recommendation as the sidewall height depends on series and width. 20's would have a really short sidewall to fit right on these cars, the biggest I'd go is 18's. And it will obviously also depend on how the car is sprung. A stock spring rate car would be much easier to take with a short sidewall than say my car, with 1.12" front torsion bars and XHD (soon to be super stock) rear springs.

I am looking at putting 18 x 9 inch wide rims on the rear of a 71 Challenger.  Would 5.5 inches of back space be to much or to little.  Does anyone have any experience with this size rim.  Also what would be the tallest tire I could put on the rear without causing a problem.  I've been told a 27" is about normal, but could you go up to a 29".
Title: Re: E-Body Tire Combos
Post by: 71cudajoe on October 18, 2009 - 11:01:57 pm
I'm not sure if this will help, but I went through quite a bit of study on wheel sizing and backspacing during the process of building my 71 Cuda. Here's where I've settled:

FRONT WHEELS: 18x8s with 4-1/2" backspacing. Tires are 245/40ZR18s. I've installed a set of Wilwood disc brakes with 2"dropped spindles on my car, and the wheels/tires have plenty of clearance. This size of front wheel and tire should mount fine on stock brakes and spindles too.

BACK WHEELS: Mine is a more custom setup here, but this is what I have: 18x9.5s with 5" backspacing. Tires are 275/40ZR18s. The rearend is a custom-built Strange Dana 60 that is 44-1/2" from flange to flange. I have 12" Wilwood disc brakes installed. I had to use a spring relocation kit to offset the leaf springs inward 3/4" to get adequate clearance for the wide tires, but everything fits great. I actually added 1/4" spacers to push the wheels out just a little... fits even better.

29s should be fine on the back.  It just depends on your width.   Just look for something that occupies the same space as a 275/60/15 and you'll be fine, it doesn't matter what size rim you use as long as it occupies the same space.

I am running 17x8 wheels with 4 3/4" BS (I think), and 255/60-17 tires, which are 29" tall and no problems with rubbing.  The problem you might run into is width, but height should not be an issue.

Title: Re: E-Body Tire Combos
Post by: tommyg29 on October 19, 2009 - 03:49:55 pm
I'm no expert, but I think about 4.75" is about maximum backspace for a rear wheel, unless you move the leaf springs, or you use a narrow tire. Maybe 5.5" on some cars due to factory tolerances and if you use a tire smaller than about a 275.
I think I have 15x8 rear w/3.75 backspace, with a 275/60 tire and theres a little more than one inch of space left, so about 5" bs would be about max for me.
I dont know how some people manage larger tires without mods. Some of the numbers I have seen I know for a fact will not work with my 71 cuda. Like I said, maybe poor factory tolerances, or slight changes from one year to the next, or both?

nzcuda terry,
love that look with the AR TTs, but theres NO way I can fit tires that big under my car. I've measured every which way from sunday, and it's not happening.
But a set of 17x9 rear and 17x8 front, both 4.5" backspace should fit comfortably with 275/50 and 245/50 rubber.
The stance is perfect also, and with my air shocks and hemi torsion bars I shouldnt have a hard time lowering my car about 1" to make it look like yours...perfect.

I've considered these same wheels myself. MagnumForce and Wheel Vintiques sell it -- their offering is very similar if not exactly what you are looking for:

I think the wheels on TobiasM's photo may be Foose-inspired, but I don't think they are the exact Foose designed wheels. Foose's wheel is called the "Challenger":

http://www.newstalgiawheel.com/wheel_detail.asp?subcat3=1081103 (http://www.newstalgiawheel.com/wheel_detail.asp?subcat3=1081103)

The wheels in the photo, I believe, are the Billet Chrysler 95 Series:

http://wheelvintiques.myshopify.com/products/billet-chrysler-95-series (http://wheelvintiques.myshopify.com/products/billet-chrysler-95-series)

The Chrysler 95 Series wheels are still expensive but not nearly as costly as the Foose Challengers.

Hi guys!

Thanks for your contributions...the last post from David lead me to the correct wheel: it`s the Chrysler 95...but - wow - inexpensive is something different: they aks 515 bucks for the wheels + 49 for the centercaps...EACH!!! Makes a set of four wheel incl. centercaps not less than 2,254 USD. wow... Oh, I fortgot: you`ll have to add $$$ for the tires of your choice.

But very nice wheels anyway.

Thanks for your help. Will see us here soner or later again ;-)))

hi every one i am looking to buy a set of pro convos but the rears are 10 inch wide whith 295 tyres on them whith a 50 50 back space he is going to sell them whith out the tyres do you think they would fit a stock 70 dodge challenger whith 275 tyres
Title: Re: E-Body Tire Combos
Post by: ShelbyDogg on December 26, 2009 - 10:01:47 am
You need to test fit them. That is the width I run on my car. You have to look in the posts several pages back. I run the springs moved in 1 inch, the b-body rear, and a 5.5" backspacing.

I was told that a 5" backspace, 15x10 would fit without moving the springs but I never tried it.
Title: Re: E-Body Tire Combos
Post by: tommyg29 on December 30, 2009 - 08:44:59 pm
I now have 15x8s in the rear with 275/60 rubber. I think the backspace is about 3.5" and I have about 3/4" clearance from the leafspring. The outer clearance is very close to the lip, so not much room there.
I want to go with ar ttIIs 17x9.5" (they dont make a 9") with a 275/50 tire, which is exactly the same overall size as my current tires.
I'm playing with the tire size calculator and I need a recommendation as to what backspace I will need with the wider wheel. Since the new wheel will be 1.5" wider, I think about a 4.25" backspace will work (3/4" more than current), bringing the rim 3/4" further in on the inside, and about 3/4" further out on the outside. This should leave the new tire in exactly the same relative position as my current tire.
Does this make sense?
Thanks.

Post by: ShelbyDogg on December 31, 2009 - 12:15:55 am
That makes sense, that's how I calculated how my tires would fit. I think you are wrong on your current backspace measurement though. I used to run a 15x8.5" with a 275/60/15.  That wheel had a 4-7/8" Backspace. If you are measuring wrong, you will get the wrong wheel.
Title: Re: E-Body Tire Combos
Post by: tommyg29 on January 01, 2010 - 11:50:38 am
before making a big mistake I'm taking the wheels off again today to remeasure very carefully. I forgot that adding the backspace and frontspace together will add up to 1/2" to 3/4" more than the width of the wheel. The wheel size is measured from the inside lips of the wheel, and backspace is measured to the outside; about 1/4"-3/8" on each side.

Post by: PlumCrazyChris on January 01, 2010 - 12:21:01 pm
I've posted this before, but here is a link to a site (I have no affiliation with the site) that lets you compare different tire sizes and rim sizes.  Its very cool.

Post by: tommyg29 on January 01, 2010 - 01:43:22 pm
Thats a great calculator. Ive been using it and it seems pretty accurate.
Just measured my rears. They are 3.5" backspace and after careful review, I think I need the custom 4-3/8" backspace. I could go to 4.5" and use a small spacer if it rubs the spring, but
I believe a 275/50-17 with the 17x9.5 TTIIs will barely fit my car both inside and out.
My fender lips have the stainless trim screwed into them, but if necessary I could grind about 1/8" off them too.
I know they arent popular, but do they make 1/8" spacers?
Title: Re: E-Body Tire Combos
Post by: ShelbyDogg on January 01, 2010 - 02:04:44 pm
When you measured your backspace and frontspace, does it add up to your stated wheel width and backspace?     

When ordering your wheels, most manufacturers measure to the inside of the wheel lip, where the tire will mount.

This could make a big difference when you order your wheels.  Maybe you can go by a custom wheel place and have them try on a wheel of known dimensions, then measure off of that.

I fitted my challenger 15x10s-295-50s under my cuda with my offset springs and b-body rear and everything fit without hitting the lip or sidewall.

Manufacturers use "offset" now on rims rather than backspace.  http://www.tirerack.com/wheels/tech/techpage.jsp?techid=101

Backspace could vary based on the width of the "lip" where the tire rests/wheel weights mount.

I don't like shim spacers in general, but the 1/8" thickness should still allow the rim to locate on the center register.

another option is to test fit late model mustang rims in the back with a bolt on spacer.  I've fitted 17x8 rims all around on my challenger that are actually for a mustang but I'm using bolt on spacers to bring me back to a 0 offset.  I'm actually looking for another set of mustang 17x9s because that's what I've found is the best fit.  I've test fitted an 18x10 with 285/40 and 5" backspace (-13 offset), but i would have been better with 5.5" (0 offset) but that was about the MAX I could fit on a stock sprung Challenger.
Title: Re: E-Body Tire Combos
Post by: tommyg29 on January 02, 2010 - 04:14:07 pm
I understand the offset and backspace are measured to the putside lip, where the wheel width is measured to the inside, so there is about 3/4" to 7/8" total difference with most wheels.

I measured the clearance from the mounting plane of my drum to the closest point of the leafspring and it came up 5-3/8". So about a 4.5" backspace ought to do it for me with a 275 tire. Problem is there is VERY limited selection for a 17" rim, unless you go to a 40 series, which I think is too low. I wanted a 50 series to give a slightly softer ride, and I think it will look better.
Any suggestions?

Hello Guys,

 I'm currently running 245/45/18 in the front and use a 4.6 inch backspaceing. I have a different inner fender well gaping from the outside of the tire to the inside of the fender well. The left side has all the room in the world and the right side is tight. It's about a half inch differnece. My measurment is taken from the outside of the tire to the inside of the fender lip. The car is straight (according to alignment machine) and suspension is new. Did anyone have any similar issues when putting on wide tires?

Maybe its necessary to run differnet offset from right to left?

Some are a little different from side to side. I noticed when putting on quarters that you can wided it a little before welding.  Have your quarters been touched?
Title: Re: E-Body Tire Combos
Post by: moparstuff on January 06, 2010 - 04:45:31 pm
The rear quarters have not been touched. The front fenders are goodmark. Its more noticeable in the front but the space issue exist in the rear as well. Looks like the whole body sit closer to the right side than the left. The car comes up sqaure on alignment machine and chassis machine. Even looked at the K-Frame and looks to be bolted in sqaure.



 Strange Stuff. :clueless:
Title: Re: E-Body Tire Combos
Post by: PlumCrazyChris on January 06, 2010 - 06:50:49 pm
I'd say your fenders are just out of alignment when they where installed.  There is a lot of play in those things.  I got my car painted and the doors and fenders were rehung and they look great, but there was about a 2" gap when I tried to install the front valance panel.

good luck,

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from [url=http://www.jegs.com]www.jegs.com[/url] All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries.  :thumbsup:

Cheers,
NZ440R/T

This is exactly the tire/wheel combination I'd like to run on my 73 Barracuda, but in this thread I've seen questions about whether there is a difference in the wheel well clearance between Barracudas & Challengers?  Also, does this vary by model year or is it the same for all 70-74 models?  Any help would be greatly appreciate!

Thanks, Jim

This combo should work with all e-bodies. I'm pretty sure that the 15x7 have a 4" backspacing like the stock rallyes. 275x60x15 is a common rear tire that many put on.

Finally got my two new fronts mounted...still waiting on the custom offset rears.
The fronts are ttIIs w/245/45-17 bfg g-forces. These tires are MUCH more responsive than the radial t/as. A little stiffer too cause of the 45 sidewall instead of the 235/60-15s I had on there.
Wheels are upgrades from 15x7 to 17x8, and the backspace was 4.5", now 4", so these tires fill the fender much better.
Now I need to drop the front about 1" and will research how to adjust the torsion bars. Hope I have enough room to do so.

Special order offsets for the rear?  Who offers these and what is the size & custom offset you're getting to make things fit?  I'd really like to see pics when you lower the car, my only issue with the really low profile tires is the gap they leave filling the wheel well.  60's don't have that issue but also don't handle as well as the 45's & 55's.  Great look so far!

american racing torque thrust IIs are 2 piece wheels and are available in custom offsets. Mine will be 4.5" backspace to allow for the most wheel and rubber I can squeeze in back there without relocating the springs. Every car is slightly different, and some have had mods done to them without the current owner even realizing.
Ive already lowered the front another inch since the picture, and it gives me about 3.5" clearance to my header flanges underneath. Lowering an inch took 2 full turns of the torsion bar adjusters on one side, and 3 on the other to even it out, with the fender lips at 24.5" above the ground. I may even raise it a little if I can once I get the rears on there next month.

I don't see it happening on the front with 15" rims.   I doubt you can tuck the rims back in far enough.  Mike Tyler has 275s on the front of his, but I think they are 45 series.  That shorter tire probably makes the difference.   You can see his setup here.   http://www.cuda-challenger.com/cc/index.php?topic=42140.0

Tire manufacturers have wheel width recommendations on their websites.  Looking at a few, looks like 255's are about the max recommended for an 8" rim.
Title: Re: E-Body Tire Combos
Post by: PlumCrazyChris on January 26, 2010 - 11:52:07 am
Thats true Engineers, but there are lots of guys running wider tires on the street then what is rated as far as rim width with no problems.  How many guys on here run 275s on an 8" rim.  This may be naive, but if the tire fits on the rim, I say go for it. 

If your running autocross or road racing, then you should know what you need better then us.

I would very much appreciate seeing pictures when you're done, especially after lowering the car to where you want it.  The problem I've seen on some of the cars running larger rims and lower profile tires is that they don't fill up the wheel wells leaving a gap on the top and sometimes sides.  I like what I see with your fronts so far and would appreciate a picture just showing the difference now after you lowered the front.  On the backs, so you're staying with 8" wide rims with more negative offset in the back?  Didn't know if you were trying to fit 9 / 9.5" rims in back with the additional backspacing.  One last thing, how difficult was it to order the custom rears?  How much extra where you charged?  Looking great so far, thanks for the info.

Road Runner:
I'll try to post an updated picture, but for now you can just imagine it about 3/4" lower than my prior picture of the front half of the car, and yes it does have more space in front and back of the tire.
I ordered 17x9.5" rears with 4.5" backspace. As I mentioned, I have 5-3/8" from the rear drum mounting surface to the closest spot of the leafspring, so 4.5" backspace should barely work for me. If it rubs slightly or comes close to it, I can add a 1/8" spacer to push it out a little, and still have at least 1/2" of thread on the studs. Worst case I can relocate the springs, which I dont want to do, or I can install longer studs and use a slightly bigger spacer. It should be very tight but I expect at least about 3/8" from the inside of the tire to the spring.
If its a 2 piece wheel design it can usually be custom ordered, and yes it is more expensive, by about $70 per wheel in my case I think, and it takes an extra 6-8 weeks for delivery. Thats why I'm still waiting for the rears, and I got the fronts in 2 days.
Depending on the size of the tire, I think all stock rears can handle 4" backspace, and some cars can handle up to 5".
Your mileage may vary. :bigsmile:

Chris, my only concern is that we all got into that habit when we had a LOT more sidewall to play with.  When you start fitting 40 or 50 series tires, you're talking about as much as 1.5" less sidewall than the classic 275/60R15 on a 15x8.

about a 255 wide tire.  Look at a tire manufacuter's specs for tires.  The shorter sidewall is much less forgiving.  I have a set of 275/40ZR17s I tried fitting on a set of 17x8s... They WOULD NOT BUDGE...  Now a different manufacturer might be able to.  or a taller sidewall...  Now I'm stuck either finding new rims for my used race tires, or new tires for my used rims...

btw: I fit a 16x8 with -11 offset (about 4.125" BS) and 245/50 tires on the back of my Challenger and it BARELY rubbed on one side (wheel lip).

That little bit of lowering made your wheel/tire combo look WAY better.  I bet it does handle like its on rails compared to the 60's you had on before.  Darn, I was sure I was going with 15" rallyes, now I'm not so sure!!!  Thanks for the new pics.

finally heres my setup and pictures. I mounted them today: :bigsmile:
American Racing Torque Thrust IIs with BFG g-force T/As
Front:  17x8" w/4" backspace and 245/45
Rear: 17x9.5"w/4.5" backspace and 275/40
Clearance is great all around

These two tires are roughly the same overall height at 25.7", and though I'd prefer 50s front and rear to fill the wheel wells a little more, and maybe give a slightly softer ride, you cant really find that size in a 17". Not with rubber that I like.
I hope you enjoy the look as much as I do. :cheers:

Looks like you could have gone another 1/2" inside and probably outside too. That would have put you in a 3xx by 17" size. Did you look into anything wider?
Title: Re: E-Body Tire Combos
Post by: tommyg29 on January 29, 2010 - 07:18:52 pm
thats a 10-4
No I didnt think it would work. I thought FOR SURE this combo would barely fit, but you are right
when it comes time to replace I hope to go even wider on the same rims

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from [url=http://www.jegs.com]www.jegs.com[/url] All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries.  :thumbsup:

Cheers,
NZ440R/T

Well, I pulled the trigger on exactly this wheel & tire combo on my 73 Barracuda and it looks awesome.  Curious though, the tires don't extend into the wheel wells as deep, at least they don't look like they do because there is a slight gap between the tops of the tires and the lip of the wheel wells both front & back.  I'm not sure if this is due to differences between the wheel openings on Challengers vs. Barracudas or if my suspension is higher or you lowered yours.  Any thoughts?  I know the front can be raised & lowered by adjusting the torsion bars but the leaf springs pretty much are what they are unless altered and mine look stock.  I'm not sure I would change it if I could because I like the look right now, but just wondering why your Challenger looks like its sitting down on the tires a lot more than mine.  I'm out of town right now, but I'll post some pics next weekend.

Thanks, Jim

The stock rear leaf springs made the car look like it was squatting in the back, and it did sit pretty low.  Yours might have newer leafs or aftemarket with a couple inches of lift.  Like you said on the front, it can be raised and lowered as much as a couple inches with the torsion bar adjustments, or you can put in a lowering kit if you want.

I think you may be right about my leaf springs.  The little old lady (seriously, no joke) who was the original owner had a trailer hitch on the Barracuda and told the guy I bought the car from that for the last 10-15 years the most she drove it was to tow her boat!!  Not too many Barracudas towing boats to the lake now days.  So even though they look stock, I wouldn't be at all surprised if the leaf springs are 440 HD versions, etc.  I know it doesn't sit down at all in the back and is pretty stiff pushing down on a back corner, etc.  Thanks for the heads up on your set up, I don't think I could be happier with how mine came out.

Later, Jim

Yesss!
finally heres my setup and pictures. I mounted them today: :bigsmile:
American Racing Torque Thrust IIs with BFG g-force T/As
Front:  17x8" w/4" backspace and 245/45
Rear: 17x9.5"w/4.5" backspace and 275/40
Clearance is great all around

These two tires are roughly the same overall height at 25.7", and though I'd prefer 50s front and rear to fill the wheel wells a little more, and maybe give a slightly softer ride, you cant really find that size in a 17". Not with rubber that I like.
I hope you enjoy the look as much as I do. :cheers:

Hi Jim, I had my leaf springs re-tensioned (twice now) to achieve my desired sitting stance. Nothing worse than a fat sagging ass and nothing worse than a 4x4 far too much 1980s style rake, IMO. Just a little time and being fussy got me MY perfect stance, I'm happy.

15x8 w/3.75 will fit the rear, but tight (I had 15x8 w/3.5 and 275/60 bfgs), but fronts will not without trimming the fender, and even then it might not fit or look right.

I am amazed that they do fit.  We have 15x8.5 with 3.75 BS and 275/60s on the rear of our Super Bee, and they just barely fit, and those wheel wells are huge.

I have a 73 440 'Cuda and it currently has 14 inch ralley wheels with P225 on it. I want to put cragar SS on it. I am looking at P235-60-15 on front and P255-60-15 or P275-60-15 on rear. I like the way LL_Davis's Challenger on this site looks and sits with cragars. I would like to know what size tires and back spacing that Challenger has. I do not want the tires to stick out of the wells and I want a slight rake to the back. I talked to Summitt and the cragars they sell have 4.25 and 3.5 bs. Suggestions?

Welcome aboard here.   :wave:

You would definitely need the 4.25 inch backspacing to use the size tires you are considering. I believe the Davis' had 275-60-15 tires on the back.

Also, you may need to get your rear leaf springs re-arched, or get leaf springs that are over stock height to get the desired rake look you want. I was in the same boat as you once. I only have 255-60-15's on the back of mine, but I put leaf springs that are 2 inches over stock height on the back.

50s on the rear with a 15" tire is going to be too short, no matter how wide (295 is pretty much as wide as you can go with a stock suspension).  Your best bet is probably 235/60-15 front and 275/60-15 rear.

Yours looks great! :2thumbs:  Mine has the same rake, just an inch or so higher on each end.  I've got to get some new pics & post them on this thread, but I credit how well this wheel & tire combo looks on yours for helping me decide to do the same on mine!  If I ever get serious about handling, I will probably go for exactly your stance.

Why thank you Jim! It's a pretty basic appraoch, cover the top of the tires (not too much = sag) and have a nice 1-2" rake to keep that arse end perky and light looking. You can see the rake best by following the sill line.


Be sure to post photos when you get the chance, we like eye candy here!! :cheers:

Those look great, I bet it handles much better too.   What backspacing did you use?  4.5" for both? 

I like the 18" rims better then the 17", they seem to fill the wheelwells better.    I wish you could get 45 series for the back to give it a little more sidewall, but what are ya going to do...

I'm shopping around for new wheels/tires for the Challenger. I've been leaning towards the 17" American Racing AR500s with 285-40-17 and 225-50-17 tires. More I look at the 18" combos though, the more I like them.

There's a narrow selection of 17" tires that get the tire height to 27", but you sacrifice width. A 255-50-17 comes to mind.

Just thinking out loud....

Hi Terry, thanks for the info bud! At this stage I won't bother you with coming around but thanks heaps for that kind offer, something of which closer to the date when we get it running (end of the year) I may take you up on. You are right, I am one for 15" white letter setups but as far as modern rims go, your setup sure looks smart and sits well, you nailed it. ;) Ps: I got your email thanks mate but since I've replied here, won't repeat myself by replying to that.

gcbeeper-   the combination of tire size AND rim with PLUS the super stock springs did the trick for the back - and the front was one size lower in the wheel-  I think we had 14's on there...  I think the receipts I had from Summit are long gone- and so are my old posts where i documented it-  but Mike is probably right-- he has a great memory
Title: Re: E-Body Tire Combos
Post by: Redline on March 01, 2010 - 06:59:10 am
I think the back was 15x7 the front was 14x7  we tried a 15x8 but the tire was too wide.  as i remember-  the large tire and 7" size made it taller so it fit right --  and 4.25 -- also we did a disc brake conversion and i recall we adjusted some things there

Ok, finally my chance to contribute to this thread.  After much agonising and measuring, and measuring, and measuring...well you get the picture...I finally bit the bullet and bought new wheels and tyres for the Barracuda.  Had been running the original 14x5.5 Magnums with 225/70R14s all round but wasn't happy with the skinny look or empty guards.  I had always liked the Keystones and was looking to go a Day Two period-correct look so this is how it ended up.

15 x 7s with 235/60R15 BFGs on the front.
15 x 8s with 275/60R15 BFGs on the rear...but my diff was off-centre so clearance on the right side was the problem.  Had to get both rear centres relocated 1" to max backspace possible (4.85"), and also had to skim 5mm off the mounting face of the RH wheel.  End result was pretty even spacing each side and no rubbing as yet.  Cheers!

Post by: Tom Quad on March 08, 2010 - 10:32:29 am
I am really confused as to why anyone would put a tire wheel combo on these cars that compromises the ride and handling as well as the "look" of the car.  I guess bigger is better and looks cool with modern day type wheels supersedes a good ride, great handling and looks like a 1970's muscle car...then again if you get your jollies at 10-14 seconds at a time or just pedal back and forth to car shows and cruises just ignore me and do what you like.

The right size  tire and wheel combination for most mopars is 16x8 on a 4.5 backspace with a 255-50-16 tire.  26 inch tall tire with 10 inches of tread. A 17 inch tire in the same diameter has a sidewall that is too short.  27 inch tall 10 inch wide or more tires tires create fitment problems and compromises in clearance, handling, stopping etc. If you spend any amount of time at the road course [like I do] the American "track cars" mustangs camaros and the lone Cuda[me] run a 245 or 255 -50 - 16 competition tire and they run fast and hard.  Faster than me... There are good tire choices available in 255-50 ZR16.  I just bought 8 of then for a couple of mopars, 70 Cuda and 70 Charger.
BF Goodrich   
 *  Size: 255/50ZR16
    * Blackwall
    * Serv. Desc: 99W
    * UTQG: Treadwear: 340
      Traction: AA
      Temperature: A340 AA A

    * Price: $119.00 (each)

I don't understand the bigger is better mentality that pervades this subject. It should be what fits without compromise and looks right for the 70's. With the hood closed and the car not running my p-o-s looks just like it should...an old muscle car with 5 spoke mag wheels.  As I tell the new comers to my track event-don't let looks deceive you...
Title: Re: E-Body Tire Combos
Post by: 73Chally on March 08, 2010 - 11:01:46 am
You talk about traditional wheels/tires for a 70s look, but they never had a 16" wheel back then.  If that size suits your needs best, then great, but what's wrong with a 17" wheel/tire package, or the traditional 15" package?  Most people don't autocross their cars, but we do drive them so obviously fit and look are high on our list.  If you want to stick with the 70s look, then get a set of 14 or 15" Cragars/rallyes/Keystones, etc.  Otherwise, to each his own.

What wheels did you go with?  The tire size you use is for a C4 Corvette, so definitely plenty of them out there.
Title: Re: E-Body Tire Combos
Post by: HP2 on March 08, 2010 - 01:11:25 pm
I don't understand the bigger is better mentality that pervades this subject.

I thinkit is much more than simply bigger is better and I don't think I could hit on all the variables that seem to drive those decisions, but I don't doubt that is part of it. But I think a large portion of it is that so many, many owners are casual owners in that they use the car for a simple pleasure vehicle with some improved capability, therefore they do not do the research to fully understand capabilities and options other than typing on a web board about "what can I fit?" types of questions.

A good example of this is all the various threads we all see on various boards about how I want to make my car handle more like a modern car and will this $5000 suspension do that, when in reality all they really need is a $50 alignment.

So, IMO, a lot of the 17" and 18" wheel migration is because of the proliferation of cheap tires and retro styles that are now available in those sizes, which means the average, "casual" owner can step up to some improved grip with a good look for very little brain power and credit card damage.

There is also the migration towards bigger and brigger brake rotors as well, which necessitate bigger wheels to accomodate them. Now, does everyone who buys a 13 or 14 inch brake assembly fully utilize its capability, I doubt it, but if it makes them feel better having them, then buy away.
Title: Re: E-Body Tire Combos
Post by: tommyg29 on March 08, 2010 - 01:29:12 pm
dont forget that the style today is larger than it used to be. The styling is such that people need to see the wheel well filled out all the way, which is very unlike the old days. In those days the biggest car tire you could buy was 15". Now economy cars come with bigger than that. Call it a fad if you want but I dont think tires and wheels will be getting smaller again in my lifetime, unless we all have to start driving electric carts.
So yeah, with me anyway its just as much about the look as it is anything else.

I'm looking at the same wheels for my Challenger, but possibly running 285-40-18s out back. Is there enough room? Do you get any rubbing with a full trunk? I'd like to be able to ditch my air shocks with no worries of rubbing when I chuck a cooler full of brew in the trunk.

Definitely too small.  A stock 255/60-15 tire is 27" tall, while a 255/50-16 tire is 26" tall.  That tire might be good for autocrossing, but will look too small for your cruiser.  Also you can figure on 200+ RPM higher at highway speeds.

No racing for me.  Mine will be for driving comfort and to fill up those wheel wells!

EDIT: Well guys I've FINALLY found my wheels.  I'm going with the Polished billet Chrysler Rallye wheels from Year One.  Either 17"x8" with 5-4 1/2" bolt pattern and a 4 1/2" backspacing or 16"x8" with 5-4 1/2" bolt pattern with 4 1/2" backspacing.

I am looking to fill my wheelwells but may consider a small tire up front for stance reasons.  Any suggestions on the tire size(s)?

My car is a '70 Barracuda 'vert with a 360 auto and a 8 3/4 rear at 3.55.  Will I need to make any adjustments back there to get everything to fit?  :dunno: Also, I may be installing the Dana 60 someday so I want to end up with a package that is in line for both rears. :dunno:

Im going with:

front: 18x8 w/4.5bs(+2 offset)  245/45-18
rear: 18x9.5 w/5.1bs(-4 offset) 255/50-18

does anyone forsee any issues I might have? My only concern was my clearnce on the leaf side...

I'd think you're going to need to run offset hangers and shackles in order to fit those rears. 18x9.5" rims with a 5.1 BS is probably going to put you into the leafs.

I agree. I have a bit different setup. My wheel is an 18x9, with 5.9" of backspacing. With that I have 7/16" worth of wheel spacers and run a 295/45/18 series tire. If someone wants to figure out the difference in size from mine to his. Feel free! Mine fits a stock well/spring location..

see i figure if guys are able to fit a 295/45-18 which works out to a 11.6" wide tire with a overall high of 28.5"...

than me running: 255/50-18 which works out to a 10" wide tire with an over all high of 28"

should technically fit... No?

i figure that i should be safe on both sides because im not running as wide of a tire as the guys who have altered there axle/ spring position...

once again thank you guys for any and all input you've got

I don't think the tire width isn't the issue, as much as it being located in the wheel well properly. I probably have 1/2" on each side of the tire from the spring, to the 1/4 panel. So not much room to mess with. Crunch your numbers.

Yes. 7/16" spacer, 5.9" backspaced 18x9" wheel. (with 3" studs for good lug thread engagement since the alum wheel hub is so fat)
Title: Re: E-Body Tire Combos
Post by: greenzeppelin on April 03, 2010 - 09:57:09 pm
I just did some quick number crunching...

if your running a 18x9 with 5.9(151mm) backspacing & a 7/16(11.1mm) wheel spacer than your new backspacing would be 5.5(140mm)

and you said you've got 1/2 of clearance still than i should have plety....No?

thanks again

You'll have a 1/2" less backspacing, and a 1/2" wider rim. Sounds like you'll be an 1/2" or so closer to the 1/4 panel? Which depending on the tire, you'll be very close to the 1/4 panel. In comparison to my setup.

Either way I think it will be close. When I bought my wheels I wanted more backspacing than I needed. You can always take it away by adding a wheel spacer, like I did. You cannot go the other way. If it's too much into the 1/4 panel, then you are SOL. Too much into the spring, you can space it off.

Just my 2cents. I number crunched the best I could and mine is working out well.

See and your rears fit pretty tight right?

your tires are 11.6" wide where as the tires im going to run will only be a 10" wide so that extra 1.6" is my buffer i think..

beacuse like you said ill have a 1/2 less backspacing w/ a 1/2 wider rim than your running..

That is an advertised specification on the tire width. Depends on the rim width as well.

(http://www.solidbushings.com/challengerproject/hoodwheelstest.jpg)

In the back I can go to a 9 in wide rim by going to 5.25" BS and trimming the fender wheel lip a little bit (have a couple rough spots from the stamping).

I'll probably end up going 16x9 in front and 16x10 in back for when I get serious about racing.

& how much space to the leafs?

about 1/4" to some rough edges leftover from the 1971 stamping process.  sticks out at least another 1/4" over my wheel well trim in areas

about 1 inch

yes.  if I trim the excess sheetmetal I will be fine, but it's tight.  When I decide to go to 10" wide rims I will be relocating my springs inboard and running custom 3 piece rims.

How much ground clearance do you have with those 17" rims?

Post by: GoodysGotaCuda on April 17, 2010 - 12:20:56 am
How much ground clearance do you have with those 17" rims?

I'd imagine it to be inconsistent between vehicles based on engines, springs (new, old, aftermarket) and how high the torsion bars are cranked (or not). Tire height is the important part. My front 17s are 27" high and my rear 18s have 28.5" tall tires on them. Probably more 'ground clearance' than most 14" or 15" setup ebodies. I think the factory 14" tire my car had was a 26" tall tire..
Title: Re: E-Body Tire Combos
Post by: cudazappa on April 17, 2010 - 07:28:10 am
How much ground clearance do you have with those 17" rims?

I have about an extra 1/2" over the stock 14" tires.  Originally my car came with 195/70R14s (24.75" tall).  The 17s are 25.75" tall.  And I lowered the front back down to where nothing rubs (yet).  But I have more room under the K then when I bought the car (from the original owner).

I'm still halfheartedly searching for a set of 17x9s for my 275/40 race rubber....  and that's just a little shorter than what I have now...

Of course I also have a pair of 235/60 on 15x7 and another pair of 255/60 on 15x8 rallyes should the fancy strike me.  BTDT right now...

Well New rims & tires, second set actually cause they sent wrong bolt pattern first time, showed up today!!

The cars not mobile right now so i could only mount them and see how it sat & check clearance, to see if my homework is correct really!

But as stated earlier, im running

Tires: Mickey Thompson Sportsman SR (slight flame pattern!!)

 Front:  26 x 8 x 18
 Rear:  28 x 10 x 18

Rims are Boss 338

Front: 18 x 8,  w/4.5bs  (+2 offset) 
Rear:  18 x 9.5 w/5.1bs  (-4 offset)

Im happy to say they fit!! at least the rears do!

Im glad I went with the 10" wide & not the 12" wide tires.. i have a 1/2" of room on the passenger side & about an inch of room on the driver side between the springs & the tire sidewall.

M/T S/R 26x10x15 front tires on 15x8 rims with 4.5" backspace. 26x12x15 rear tires on 15x10 rim with 5" back space. Rear springs moved in .75" with B body rear. 0 arch rear springs. Car has been lowered about 3" overall and I may go another couple inches if i can pull it off. I could go at least another inch wider in back, mabe even 2" if I rolled the fender lip. I could use another .25" of back space on the front and I could add another inch of tire up there, but hey, I got these wheels for $30 each, so I can't complain too much.

The e-body rear axel is winder then the b-body axel as fare as I know. So you should be able to fit wider tires with a b-body axel.

Title: Re: E-Body Tire Combos
Post by: HP2 on June 20, 2010 - 10:39:02 pm

The trick to using a B body rear is that you move the springs in, the B body rear sits right on top of them, and with no other mods, and you can put 13" wide tires under there. If anything other than this was done you the rear, then you have to figure out what rim back space and tire sizes will fit on a case by case basis. BTW, 65-67 B body rears will require less back space than similar 68-70 b body rears. All of this is explained through out the forum, and if your still confused, there is plenty of help here to sort it all out.

but,
i went for a ride in a friends road runner with 18 wheels, and i was very surprised how rough riding it is ?
it seems to handle very well, but man, is it ever bumpy and choppy?
is this normal with the big wheels or is something wrong with his car ?

buddys road runner looks really stupid with the 18 wheels and low profile tires, i think the car may be to big?

I have 17s with lower profile tires (245/45 up front) and the lower profiles definitely give a sharper ride than the oem tires!
I also have big torsion bars and hemi springs, so every pothole or bump jars my bones and makes me cringe.

i have 245/45 17s as well, and I really need to up the $$$ to bilstein, koni, or QA1 shocks.  Problem with the shocks spec'd out for the e'body, they aren't designed with the wheel rates that we install into our cars.  1"+ t-bars and bigger sway bars need better shocks.  1" is just passable right now in my car... and I want to go HIGHER on my wheel rates.

i recieved my set of boss 338's a little while ago.. for the second time.

they sent me the wrong bolt pattern the first time!  So needless to say, as soon as i got this set i mounted up the rears & dropped the jack stands to see how they fit in the wheel wells & how close to the spring they were..

*keep in mind my car has had a small shackle lift at some point in its life*

*I went with a mickey thompson 28x10x18*

-on the passenger side I had a 1/2 of clearance between the tire and spring pack..
-on the driver side i had a lttle more

-and as far as i can tell, with it still sitting in the garage, they sit nice on the outter lip & wount have trouble for clearance or it sticking out to far

hey 05srtcuda..  I wonder if the rear quarters are wider on a challenger than on a cuda? because mine are do not stick out that far

My 'cuda has SSBC disc brakes in the front, so many the dust caps are smaller then the stock ones. The look the same as the drum brakes had.

Hey Greenzepplin what have you done to raise the rear end so much.  Do you have air shocks. Also I have 17x8 4.5" BS Cragers on ther front of my 71 Chally with 245/45's.  I want to lower the front a little but they rub on the outside especially when you turn the wheel.  I've got 17 x9 on the rear with 5.5" of BS with the Dr. Diffs spring relocation hangers.  Plenty of room with 295's on them, but I have been thinking of getting new rims,all 17's but with a 5.5 " BS on the front so I can lower it a little.  How much were the Boss wheels you have.

Here is my contribution.
18" KMC Hot Wheels "68" wheels.
7" backspacing
8.5" wide.
2" adapter needed to clear the spring, and 1/2-3/4" away from the wheel lip.
I bought my adapters from Adaptitusa.com.

Big Mike is very helpful, and a great Mopar enthusiast. I recommend dealing with them.

Whats the most backspace you can put on the front wheels.  I can't seem to get a 17x8 rim much inside the fender well.
Title: Re: E-Body Tire Combos
Post by: HP2 on October 28, 2010 - 02:42:23 pm
I've had 4.75 backspace on a 15" rim, and that is as close as I could go to the upper ball joint. In a 17", you may be able to get away with 5", bu tI'm not sure.

See what Mike used; http://www.cuda-challenger.com/cc/index.php?topic=42140.0

Post by: cudazappa on October 28, 2010 - 02:53:58 pm
I am running a little over 5" backspace right now on 17x9 rims on the front.  On 17x8s 4.5" worked fine, except on hard turns at full lock and suspension movement (rubbed at the very top).  So both combos rarely rubbed.  I'm going to increase the backspace in the front when I go to 13.1" rotors in the front.
Title: Re: E-Body Tire Combos
Post by: Kevin71 on October 29, 2010 - 12:36:38 pm
I have SSBC disc on the front and was told by Coy wheels that the add about a inch over the drums.  I have 17x8 4.5 back space.  Have about 1/2 inch before it hits the upper A arm.  The car has to be raised a least a inch above the wheel to prevent it from rubbing when you turn the wheel.  I tried a torq thrust m with 5.62 inch of back space it hits the upper A arm.  Added 1/2 spacer and still hits the A arm.  So I am going to try a 17x7 with 4.5 inch of back space and see if I can get the front down a little.  I am running 17/45/235s on the front.

I have just got a set of Coy's 18/9.5 for the rear with 5.5" of back space.  I was thinking of putting a 275/55/18 on them which would be right at 31" tall.  Would these be to tall.  I wanted to get the rear end to sit a little higher.  I hope to get all of this put together within the next week and get some pics posted.  I think the taller tires would fill the fender wells good.

You might want to run a 31' Tall tire through this calculator with your trany/rear and see how it effects performance before you buy anything.

Post by: Killer_Mopar on January 13, 2011 - 03:05:25 pm
I thought I posted in here already, but couldnt find it? Anyhow, I took this from my restomodification thread....

I ended up going with 18x10 Cragar 612 series S/S wheels. They are basically the same wheel as the standard S/S wheels except they are all aluminum and polished instead of chromed. They are MUCH lighter than the hybrid design. The fronts are the hybrid design and are 17x8 (4.5 BS - 38lbs a piece) with 255/45/r17s. The rears are 18x10 (5.25 BS - 24lbs a piece) with 285/40/r18. I went with a 68 B-body rear end with Dr. Diff's 1" offset kit. The tires are Nitto 555s and without the relocation kit - they would definitely rub. As it sits right now, they have a little less than 1" clearance between the wheel and the springs and ~.5" between the wheel and the lips. I also lowered the car 1" in the rear via Dr. Diff's relocation kit. After driving it, I would recommend 245 for the front OR an extra 1/4" of backspace. I have minor rubbing issues when turning and hitting bumps, which caused me to raise the front a little - I plan on rolling the front fenders to remedy this issue and lowering it back to where I want it. The rears have no problem whatsoever with the relocation, in fact I have room for a wider tire - I know a 295 will easily fit and I think with perfect backspacing a 315 will even fit. These pics are kind of old as I still didnt have my exhaust hooked up.....

Hi All,
Well, I pretty much read all 33 pages and still have questions.
My '71 Barracuda came with Rallye 14x7s in all four corners.  Last year I oinstalled Viniques 15x8 with BFG 225/60 on the rear.
Well, not overly happy with the over all appearearance.
I'm still rebuilding the front suspension, so I can't just move the wheels around.  The car is stock, just replacing parts and Edelbrock IAS in all four corners.
Here's the question for you: Will the 15x8 Rallyes with BFG 225/60 work on the front?

Thank you

I have 235/60/R15 with 7" rims on the front. I have seen 8" rims on the front of a Challenger before? Can't say for a Cuda?  I'd say tire size is an non-issue, just the rim width is unknown?
Hope this helps?

I think the fronts you need to make sure you have enough backspace with a 15" rim because of the upper control arm if I remember correctly.
The stock backspace is obviously ok, but too much bs and the rim will hit.

First - thank you very much for your assistance  :worshippy.  The tire/wheel game can give you a headache.

Looking at Summit online, they have two Series 56 Rallyes 8x10 (for the rear of the Cuda)
The first offers a 5.0 inch backspace
The other has a 5.5 inch backspace
Since I have no clue what a backspace is, let alone which is better/needed, I ask ya'll for assistance (again)
And, after answering the Wheel Backspace question, what size BFG Radial TA's?

And, as long as I'm asking, Summit has 15 inch trim rings for the 56 Series,but, there's a note that says "Fits 15x7."  Does it matter the width of the wheel?  I wouldn't think so, but I'm asking.

Again, all four corners are stock rebuilds and have Edelbrock IAS shocks.

Thank you in advance

If your rear suspension is stock, a 275/60/15 tire on a 15x8 rim with 4.5" backspace is about as big as you can fit without making other modifications. The trim rings will fit a 15x8 rim but you will have a 1 inch gap. I still can't believe nobody has made a trim ring to fit an 8 inch wheel correctly.

The back tire are yokohama's and my suspension is stock with no wheel mouldings. I have about 1/2" on space between tire and spring and just a little less than that on the out side. I havenet mounted my fenders in front yet so can say clearence on the out side but inside pleanty of room no rubbing on full turns.

Overall, a decent choice for a stock appearence, however, if you have the option, get another tire. BFG has an ongoing issue with quality of tire roundness and balance with their old TA line. Add to it that their tread design and carcass compound are over 20 years old, and it doesn't take much for you to find better tires out there.

hi guys thanks for the comments ,  im glad you like it carl i know you like that old school look give us a call sometime i can bring the car around for you to have a look .anyway  the wheels are made by eagle alloys they are a boss  motorsport wheel   front b/s 4.5 and rear b/s is 5.5  also the rear  end is a stock e body 8 3/4 with no mods  cheers terry :nzflag:

Awsome combo!

How did you get 5.5 inches of backspace for the 18x9.5 Boss wheels... they only advertise 5 inches on their websit?
What clearance do you have with the fender lip because I have disk brakes that would remove 1/8 of an inch from the backspace...
What brand of tires do you have? Do you think that 45's would fit?

15 " Cragar SS front       Summitt CRR-61715 Cragar SS 15x7, 5x4.5, 4.125 Backspace
15 " Cragar SS back       Summitt CRR-61815 Cragar SS 15x8, 5x4.5, 4.25 Backspace
BF Goodrich tires front Summitt BFG-54712 Radial T/A P235/60R15 98S
BF Goodrich tires back Summitt BFG-71728 Radial T/A P255/60R15 102S

This is exactly what I wanted. Just a little rake to the rear end.

Title: 275/40/17's with 17x9's
Post by: 72bluNblu on October 19, 2011 - 03:34:29 pm
Ok, thought I'd put my new wheel and tire combo up.  :grinyes:

17x9" Summit Legend 5's with 5.0" backspacing all the way around  http://www.summitracing.com/parts/SUM-141-7965GM0/ (http://www.summitracing.com/parts/SUM-141-7965GM0/)
275/40/17 Toyo Proxes 4's (all). 26.1" tall

Rear suspension:
Dr Diff 1" offset hangers and shackles
'68-70 dimensioned B-body rear

Front suspension:
Hotchkis tubular UCA's
Magnumforce 2" drop spindles
-1* camber, +4.5 degrees caster, 1/16" toe in.

Ride height: 24 1/4" from the ground to the top of the wheel arch at the front hub, 24 1/2" at the rear.

Initially I had a little rubbing at full lock on the passenger fender at the wheel arch, that's pretty much taken care of with the negative camber and a little fender lip rolling at the top of the arch on the passenger side. Never had an issue with the driver's side, must be a Mopar quality control thing. The rim combo should clear with stock front suspension as well, if anything the drop spindle hurts my tie rod clearance. Stock suspension might be able to get away with 5.25" BS with this combo, I have plenty of clearance to the frame in the front. It will NOT fit with "U" shaped tubular A-arms, the rims hit my CAP tubular UCA's just before full lock. Tires in the back are clear by a couple inches in both directions, I wanted to run the same size tires all the way around, otherwise I could have gone much larger in the back.

Easily, I would think.

Some quick work with a tape measure shows that I have ~1.75 inches to the fender, and a little less than 1.5 inches to the springs with my 275's and 5" backspace. Surprisingly enough that was actually the same side-to-side! Some fender lip rolling would give you an extra 1/4" on the outside even.

A 295 is only about 3/4's of an inch wider, should fit no problem as long as you get the backspace right.

Actually with a 9" rim that's about right. -2mm works out to be a 4.9" backspace. I run a 5" backspace on mine, with just a minor rub at full lock with some suspension travel. I'll be rolling the fender lip to get rid of that...
Title: Re: E-Body Tire Combos
Post by: cudazappa on November 06, 2011 - 06:58:31 pm
whoops, late night math mistake... I meant 2 offset.  The rim is a 6" backspace and I have a 15/16" spacer (for 5 1/16" backspace)

With smooth driving it doesn't rub.  I really only rub turning into (or out of) a driveway on a hill (pre-rear swaybar)  My car is also not as low as 72bluNblu's (yet)
Title: Re: E-Body Tire Combos
Post by: dodj on November 06, 2011 - 09:33:43 pm
Guess that means I should be able to get  17x9 255/40's to work given the right amount of offset.

With your 9" rims, is a 5" backspace about perfect for you?

I think with 17x9's "perfect" is between 5 and 5.25" backspace.

I can't run any more backspace because of my drop spindles, my tie rods are as close to the lip of my rim/tire as they can be. With stock spindles and 17" rims the tie rods would actually be inside the lip of the rim, so there'd be more room. But based on my clearance to the frame, I'd say about 5.25" backspace would be the absolute most before you really started rubbing the frame hard at lock.

But 5" is definitely about the minimum backspace to clear the 17x9's and 275/40/17's. I get some rubbing on the fender lip on the passenger side at full left lock. I think rolling the fender lip will cure most of it though. And as I've mentioned, my car is pretty darn low.

Anyone know any more details about the Hotchkis E-Max Challenger T/A?  All I know is it runs 18x9 up front, and 18x10 in the rear.  Until recently, if I'm not mistaken, it was running 265/35r18 front and 295/30r18 rear.  To me this would be a near perfect fitment, and is what I am going for with my challenger.

Those are cop rims (I could see hubcap nubs on the front) and those are all 15x7 with 4.25" backspace.  The rears are definitely widened.

Super Coupe wheels are visually similar to the cop rims (no hubcap nubs) and came 15x8 with 4.5" backspace.

In the last pic (with the blue interior lights) you can see he has black painted rallyes.

Good chance the rears will rub on the rear quarters.  I run 17x9s with 5"bs (0 offset) and 275/40s and there is enough room.  In the front 245/45s on 17x8s with 4.5" bs (0 offset) is no problem.

If your 5" BS 17x9s clear the 1/4, would his 5.5" BS 17x9s be further away from the 1/4?

tommyg29,

I actually got these ideas from your post, you cuda looks really good.  But i think there is some differences between my 8.75 and your dana, i have about 6.5" on one side and 6.375 on the other side from the drum face to the springs. You mentioned that you have ~5.375"  I suppose i could play it safe and get 17x8 with 4.5bs on the rear and use 255/45/17.  I would sacrifice a little on width but be safe

Hi There
I'm new to this site and just had a couple of questions for the Mopar Veterans.  I am interested in getting aftermarket wheels for my 72 Challenger and I am just learning that there is more to it than just picking out some rims.  I understand that the backspacing is 4'' on drum brakes and 4.5" on disc. Could someone tell me if a 17 inch wheel (tasteful pattern) would be ok to mount as long as the profile of the tire stays the same?  I have never measured backspacing before but I think I know how to do it.  If anyone has a picture of how it's done that would be great.. I have a few more questions about my car but one thing at a time..

Thanks and its nice to be here

Welcome Larry:

I know this thread is LONG, but it contains lots of great information about types, styles, how to measure, etc.
Spend an hour (or two) if you have the time reading this thread and you will become an expert!
I know I added a few dozen posts a couple years ago that would really help you. There are also some links to other sites with good measuring/calculating tools.

Good luck and welcome again!

and PS
just so you know, there was a yellow 70 convetible cuda in some earlier posts within this thread about 3 years back that inspired me and the choices I made with my 71. Unfortuneately those pictures are long gone because the sponsors of the site cant store that much data, but after looking at some of the pics in here you might get some great ideas yourself.
Anyways, I am reposting my inspiring pic, which I luckily saved:

question for guys with 40-series tires, how harsh is the ride?
I was looking at 255/45x18 rears but being told to stick with a 50 'cause the shorter profiles are too stiff. That really limits the tire options as there's not many in a ??/50x18 or even ??/50x17.
I'm running a 255/60x15 now which is about 27" diameter and wanting to keep close to that so really a 40-series is out anyway but can do it with a 45-series. No suspension mods (yet).
Title: Re: E-Body Tire Combos
Post by: tommyg29 on April 29, 2012 - 09:39:39 pm
that depends on your suspension setup, but generally yes, a 40 will be stiffer than a 50 series. That much less sidewall (and air) to give. But you wont notice too much difference between 50 and 45. I say go for it.

The trade off between an older stock looking 15x7,15x8 look with 60 series tires versus the 17x8,17x9 45/40 series tires is the amount of sidewall flex you will encounter and the bigger look of the rim versus the tire.

Anything else I'm missing?


Here is my set-up:

Front - 17 X 8 Hotwheels Sixty-eight rims (4.5" back spacing) with 245/45/17 Nitto 555's

Rear - 17 x 9 Hotwheels Sixty-eight rims (5" back spacing) with 285/40/17 Nitto 555's    Stock rear width (8 3/4) saggy springs to boot.

 I may have gone cross-eyed now! I have red this thread 6 times! My question is that after spotting a deal on some goose wheels i hope the offsets work. My 70 cud a has a pretty stiff suspension and has relocation kit 3/4" . FRONT HOTCHKIS UPPER ARMS ALSO. wheels i found are 18 x 10 with 6.25 backspace, 18 x 8.5 with 5.25 backspace. After reading this thread, I feel a 1/2" spacer may make these perfect for me. tires are 275/40 & 245/40. any ideas?

Fronts should work as is, and you could run a wider tire than that too.

Rears might actually fit too if you have an E-body rear end. I have a B body rear end in mine with a 1" relocation kit, and I don't have the 1.5" of extra clearance I'd need to run 18x10's with a 6.25 backspace vs my current 17x9's with a 5 backspace and 275/40's. But an E-body rear would make up most of that space, so they actually might fit. If you have a B rear though I think you'd probably need that 1/2" spacer, maybe even 3/4".

With a stock E-body rear, offset kit and the disk kit in the back you might not even need any spacers. If you did I would think they'd be less than 1/2" for sure.

Hey all, I've looked through this thread and there are a bunch of posts that don't have images anymore. I'm probably going to go with 17x8 with 4.5" BS all the way around. What I'd like to see is some images of what those look like before I make my final decision. I'd like to have the rims fill out to the fender as reasonably close as possible. It's an awful lot of $$ to make a wrong decision and be unhappy with them.

Anyone?

Looks like 4" is a better fit. Is/was the difference on the rear about the same? I'm not looking to get super close to the fender and risk rubbing, just trying to fill them out.

Thanks.

Why not do a staggered setup?  Looks better IMHO.

17x8F, 17x10R.  Just get a Dr. Diff re-location setup.  4.5" BS F, 6" BS R.

I just did some eyeballing of a Foose wheel that my father-in-law loaned me from his Roadrunner. It's a 17x9 but I'm not sure of the backspacing. I put it on the front and it clearly needs to come out more. I like the way the 17x8 4"BS that tommyg29 posted.

I then moved it to the back and it could have moved out a little but not much. Now I'm wondering if the 17x8 with 4"BS will work all the way around. He had a Goodyear 235 50 17 on the rim and the tire sticks out from the rim a good 3/8"

Is there typically more room in the front fender than the rear?
Title: Re: E-Body Tire Combos
Post by: tommyg29 on June 28, 2012 - 09:14:38 pm
from what I remember, there is a lot more room to play with in back. If your car is stock or close to it, 17x8 will fit all around, but if you dont have the exact proper backspace up front, you may have to trim the front corner of the fender a tiny bit.
If you dont mind possibly having to trim a little up front, you can probably fit up to 17x9 up front, but out back I have seen up to 17x10 without modification.
But....keep in mind what works on one car may not work on another when you are cutting it close. Our cars are now 40 years old, and unless youve owned it the whole time, who knows what prior owners may have done to throw you off.
Im a building contractor, and my first rule is always...measure twice, cut once. Same applies to buying new wheels!

 :iagree:

I run 17x9s with 5" backspace and  275/4017's up front on my Challenger. Even sitting as low as it does it clears the drivers side just fine, but has a slight rub on the passenger fender lip. So, fitting is definitely an issue, don't assume what will fit my car will fit yours, as what fits the left side of my car doesn't exactly fit the right side.

I think with 4" of backspace and 17x8's you're right at the edge of fenders, and you may or may not end up hitting the fender there. Those specs will put the outside face or your rims in the same exact place as mine, and I have  a minor rub on the fender. But still plenty of room to the inside, I'd be inclined to run 17x8's with a 4.5" backspace (more common too!), or even a 4.25" backspace if you can find it or have it made. With the 17x9's on my car, I think 5.25" of backspace would be about perfect (with stock spindles to clear the tie rods, drop spindles won't clear 17x9's with a 5.25" backspace).

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from [url=http://www.jegs.com]www.jegs.com[/url] ([url]http://www.jegs.com[/url]) All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries.  :thumbsup:

Cheers,
NZ440R/T

Welcome Larry:

I know this thread is LONG, but it contains lots of great information about types, styles, how to measure, etc.
Spend an hour (or two) if you have the time reading this thread and you will become an expert!
I know I added a few dozen posts a couple years ago that would really help you. There are also some links to other sites with good measuring/calculating tools.

Good luck and welcome again!

and PS
just so you know, there was a yellow 70 convetible cuda in some earlier posts within this thread about 3 years back that inspired me and the choices I made with my 71. Unfortuneately those pictures are long gone because the sponsors of the site cant store that much data, but after looking at some of the pics in here you might get some great ideas yourself.
Anyways, I am reposting my inspiring pic, which I luckily saved:

what are the wheel and tire sizes of this yellow cuda?
Title: Re: E-Body Tire Combos
Post by: tommyg29 on August 14, 2012 - 10:48:48 pm
I dont know the details on that cuda. Dont think the owner was ever on this site. I think I found the picture on a local car show site. The stance and general look inspired me though.
If I had to guess I would say those are probably 17inch, and definitely AR TT2's. My car is not lowered quite that far, but close.
Personally, my opinion, the largest rims you can go with on a cuda, and still look good, are 17 up front, and maybe 18 MAX in the rear.

Fronts should be ok if you don't go crazy with the tire. You could have gotten away with a little more backspacing, but with an 8" rim you should be fine.

The rear is a pretty wide rim for that amount of backspacing. I would tell Cass to send you a B body width rear and an offset hanger/shackle kit so the springs are moved an inch in too. With an E-body width rear you're going to be really close to the quarters, if not into them depending on tire choice.

I run 17x9's on the rear of my Challenger with a 5" backspace, but I also have the B rear and 1" offset hangers and shackles.

Thought I better update Lucy's new tire setup. :biggrin: I'm still finishing her build so will grab side profile shots etc once completed. She still needs fuel tank, muffler system, interior, etc, so the rear end will drop a "tad" as well look lower than the photos below.

She has around 3/4" on the wheel lip side and 1 to 1.25" on the fuel tank side (if not more) to the inner wheel well housing. I know people can/do run 335/35s with this setup but I'm not a big fan of thin rubbers, I like it meaty and would sacrifice corner speed for better launches with more sidewall flex.



SPECS

Suspension = XV Motorsports Level II 3-Link Rear
Rims = 15 x 10" 56 Series Chrysler Rallye Rims with 5.0" BS
Tires = 325/50R15 BFGoodrich G-Force T/A Drag Radials

Thanks lads, I love it!! Yup, thanks Shelby, my 275/60s were this close to the lip, could barely slide your hand over the tyre and never had any issues. I like the look of them closer to the lip, if they sit too far inside, it makes the car look like a whale and "heavy" IMO. Can't wait to get the car done now!

That would be a 27" tall front tire. I don't think that will work out for you.

I run a 275/40/17 front tire, so you can run a pretty wide tire up front. But that's only a 25.6" tall tire, and its on a 17x9" rim with 5" of backspace. That's pretty much the max you can run with a 17" (or smaller) rim because of the clearance on the tie rod end. I only have about a 1/4" of clearance on the tie rod, and I run -.9 degrees of camber up front to keep the tire from rubbing on the passenger side fender. Never had an issue on the driver's side though.

To run a 255 wide front on a 15" rim, you'd need a 255/50/15 or maybe a 255/55/15. But you won't find tires in that size.  :grinno:

If you want to run wide front tires like that, you'll need to move up to 17" or 18" rims. Which you'll want to do anyway if you're trying to improve handling, because there's pretty much zero selection for modern compounds or tire designs for a 15" rim in any size relevant for these cars.

I've run a 245/60R15 BFGoodrch Radial T/A for 8 years now and no issues and zero rub.
Rim size is a 15x7" Rallye Rim (56 Series) with a 4-1/4" back spacing. :)

Ok let me re-phrase, 15x8 wheels with 4.5ish back spacing. I want to run same size tire front & rear and my Chally will/does has the slight nose up attitude. Best, largest tire size? I am not to worried about maximum cornering traction (nice) but shallow looks!

245/60 15 or 255/60 15 or something else?

Why would you want the exact same tire size front and rear? :clueless: One of the best combos for Challengers and the overall consensus is 275/60R15 Rear on a 15x8" rim with a 4-1/2" BS. Front is either 235 or 245/60R15 with 15x7" with a 4-1/4" BS. Fits all Challengers with stock specs. If you're trying to fit the same up front as the rear, then your rear size is going to suffer, badly. Below is my Challenger on it's old setup (same as the specs above). Hope that helps......

Have you looked at what 15" sizes are readily available in your desired sizes first? If you have some boutique size that is a low demand odd ball, chances of it being discontinued sometime in the near future are very good. You'll want to stick with sizes that have a good chance of continuing in  production for some time. This means 235/60, 255/60, 275/60 and 295/50 are your best candidates.

I run something close to a 255/50-15 on the front of mine (its actually a 26x10). I've done it with a 4.75 backspace rim and it was close enough to the fender lip to motivate me to roll the edges in a couple of places. With a 4.5"ish" backspace and a 60 series tire, you are putting yourself in position for some conflict. It isn't impossible, but it may require either a narrower rim, like Carlwalski has shown above, a narrower tire, a shorter tire, or some fender mods.

If you start running short wide or tall narrow tires, you end up with unusual combo in the rear that may look out of place.

The only problem might be that with a 275/60R15 is the diameter changes proportionally to the width.  With the MT's, you can maintain the same diameter, and increase the width without doing a lot of mathematics!  :2thumbs:

I've got the MT SRs on my car now. 26x10 front, 26x12 rear. Using metric specs, that is close to 255/50 front and 305/45 rear. Once I get it motivating under its own power again and use up some tread, I may switch the rears to 28x12 just for a more proportioned look.

This is how I know that a 255 tire up front  is one wide mother that is going to require a bit of manipulation and a fairly precise wheel offset.
Title: Re: E-Body Tire Combos
Post by: mysil bergsprekken on April 23, 2013 - 11:00:13 pm
So 26x12 fits the rear and also 28x12.
Could you also go for the 30x12 mickey thompson in the back, or will that be way to large diameter for using with stock suspension?

They can be made to fit. How stock is stock would be my question.

Here is mine with the 26x10 up front, 26x12 out back. Front wheel is 8" with 4.75" backspace. Rear 10" with 5" back space, springs moved in one inch per side and with a '67 B body housing. Also might be worth mentioning that I have oval track springs with a super stock hanger. This has moved the axle centerline back .5 of an inch, so I may be able to put a slightly taller tire than others.  I don't doubt a 30" could be put into the wheel well, but ride height and passenger would be a important consideration. For a drag car, no problem, for a street car, I don't know.  Somewhere I have a picture of this car with a 295/65 BFG Drag Radial installed, which is around 30" tall. It is a huge tire that may rub the inner wheel well in a street application where you have bumps, dips, and driveways to deal with. On a track where everything is smooth and you only have a driver, no big deal.

I almost went with 26x10 Mickey Thompson S/R's on 15x8 Bassett's but ended up going 16x8 Mini Lite replica's with 255/50R16's all around.  I'll try to get a picture up next week.  I thought $212 per tire for the MT's with out being able to find any performance reviews was too much.  Aaron Beck is also putting MT SR's on his 'Kuda' project but I don't believe he has run them yet.

Title: Re: E-Body Tire Combos
Post by: HP2 on April 25, 2013 - 09:31:54 am
I look at it this way, the MT SR is a carcass design that has been made in the last decade to fit differing rim sizes from 15 to 20. This automatically puts it a step above almost every other 15" tire that has its design roots back in the 1990s.  Add to that its H speed rating compared to most 15" S or T ratings, and it has better high speed ratings. I did call MT and talked to them about tread life and they said they have reports of mileage in the 15k range with average driving  ( no burn outs ), which tells me its a fairly soft tire so grip should be decent. Only real drawback to them is the two ply sidewall that will allow more flex, but when required, I think that can be boosted with additional air pressure. In my expeience, radials  are very stable about holding their diameters at high temps and high pressure levels, so there is no fear of growing its size by running them up to 40 psi, which would be a benefit to sidewall stability under stress. I'll have to see what high pressure does to its footprint, but I suspect it will shrink it some, so it will become a tradeoff between grip and support.

Just installed 245/60-15 up front with a 15x8 wheel with 4 1/2 rear spacing.

No rubbing anywhere but the car is sitting a little high right now and will be lowered a bit which doesn't look to be a problem with clearance.

Although not shown, the new rears with be the same 15x8 wheel with same backspacing with a 275/60-15

In the side view picture the different Weld wheel on the rear is the exact same size tire and rim as what will be replacing it to match the front.

To me 50's series tires just seem too short with less sidewall...I've even had 295/50-15's on the back of one of my Challengers before and it looked nice and wide but just too short.

The 275/60-15 has a bigger sidewall and just seems to fill out the wheel well the best but still keeps the tire under the quarter panel. :2cents:

I also have 3.91 gears in the 71 R/T Challenger with a 4 speed so I would like to have a fairly tall tire to compensate for the taller gears and help keep the car more steet friendly.

I have the Hotchkis TVS and torsion bars, and not surprising that lowering the car reduces the room for bigger tires.  BFG T/A's with 235/60/15 up front have never rubbed (was advised 245/60/15 would so didn't try them).  255/60/15 in back rubbed with even minor bumps on the street before rolling fender lip.  Now it takes a big dip or bump to get them to rub in back.

What size are your rims and what backspacing are they?
If your 255/60-15 rear tires are rubbing on the quarter panel lips I'll bet the offset on the rims is not right or your car is sitting really low.

I've had the same huge 28x12.50 ET street tires on the rear of a few of my Challengers and have never rubbed with lots of suspension travel.

I've got this exact combo of hard parts on my 74 Challenger on the previous page. I did move the springs in 1" per side as well. However, I'm using the Mickey Thompson SR tires in 26x12x15.  My tires are 26" tall, 12" section width with 10.6 tread width. The N50s are almost 28" tall, 12.65 section with 11.3 tread width. So you are going to be a bit over a 1/4" wider per side and an inch taller into the wheel well. Tight fit, but possible. You might rub up inside the well if  you carry a full complemenet of passengers or going over speedbumps, steep driveways, etc.

I have seen that gray one 72-74 challenger with the 72-74 center caps.

Any other pictures anyone has of the 17" Rallyes from YearOne on a 70-71 with the 70 or 71 center caps?

Please post tire sizes too!

Did a wheel fitment test last weekend. These are Foose wheels from my father-in-law's Roadrunner. These aren't the wheels I want, but they sure do dress up the car and get me excited about the wheels I do want. They are 17x9 with 235 40 17 Goodyear. I'm not sure what the backspacing is. The point of the exercise was to see what would fit and what offset I wanted.

The fronts fit great and filled the fenders well but the rear need to come out about an inch. I've decided that I'm going to go with a 17x9 front and an 18x9.5 rear. Still need to work out what the offset will be when I have the $$ to purchase.

235 is awfully narrow for a 9" wide rim. I run 275/40/17's on my 17x9's (front and back). And short, a 235/40/17 is only 24.5" tall.

As far as offset, you'll want pretty close to 0 offset with a 17x9". That's what I have on mine, 0 offset, or 5" backspace. A little more would be good, I think 5.125" backspace is absolutely ideal. At most 5.25" backspace, which is a 5mm offset. But any more than that and you'll hit the tie rod ends with a 17" rim.

In the back, you'll probably still want about 0 offset on an 18x9.5, which is 5.3" backspace. That will put you right up on the stock springs, you might need to run a small spacer. But much less than that and you'll be into the quarter with the tire. A 275/40/18 (or 17) is about as big as you'll be able to go without at least offset hangers, like Dr. Diff's 1" offset kit.

 Great thread guys but after several pages I'm gonna just ask.  Got a real good deal on Nitto radials for $295 shipped. 275-60-15 will go on Weld wheels, I think 8" width. Being radials will they fit any differently on my '70 Cuda than other types of tires? Thanks.

Post by: tommyg29 on July 06, 2013 - 12:20:05 pm
Tire height helps with a stiff older suspension. Anything less than 40-45 series will seriously rattle your bones and your old car.
I agree that 235 is very narrow for a 9inch wheel. I have 245s on an 8 inch front wheel and the fit is perfect IMO.
275s are a little on the wide side for an 8 inch rim, but they work. Just not my cup of tea.
The 275-60 on 8 inch welds was my exact setup in the rear when I purchased my car 4 years ago, but obviously Ive since changed.
Got pictures in this thread....search back to late December 2009 through January 2010.

PS
October 21, 2009 are pictures with the weld prostar wheels and 275-60-15s

One of the best combos for Challengers and the overall consensus is 275/60R15 Rear on a 15x8" rim with a 4-1/2" BS. Front is either 235 or 245/60R15 with 15x7" with a 4-1/4" BS. Fits all Challengers with stock specs. If you're trying to fit the same up front as the rear, then your rear size is going to suffer, badly. Below is my Challenger on it's old setup (same as the specs above). Hope that helps......

I just came back from having my 275/60R15 balanced (on 15x8 with 4.5" BS) but we couldn't put them on my rear sags so much they hit the lid with no person in the car. Guess I'll first have to fix the stance, back to the 205/70R14 for now. Wow are they tiny.  :eek7:

I thought I was going to be first. Oh well, they look great and I'm now in good company. Just got them on Friday night. One of my rear lugs cross threaded coming off and I broke a stud. Not good with a show Saturday morning. Had to find and replace it that night. Got it done.

These are 17x8 with 245-40-17 on the front and 18x9.5 with 275-40-18 on the rear. I can get the back spacing if you like. The right rear rubs just slightly (with a full load of passengers) but I'll be rolling the lip to fix that. Should be good after that.

Adding bs info:

Front 17x8 - 4.75" BS. Probably could have gone with 4 1/2"
Rear 18x9.5 - 5.125" BS

After I fixed my saggy rear by adding leafs I discovered that the 225/70R15 for the front are just a wee bit too large (diameter-wise). So I scaled back and am now running 225/60R15 in the front (on 7" rims) and 275/60R15 in the back (on 8" rims). It's on the high (and wide for the 275) side for me but I like it! Much much better than the 205/60R14 before with the saggy back. Now if only Summit delivers those center caps...  :jumping:

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from [url=http://www.jegs.com]www.jegs.com[/url] ([url]http://www.jegs.com[/url]) All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries.  :thumbsup:

Cheers,
NZ440R/T

I don't think there is so much an issue with tire clearance but more so effecting the speedo or gear ratio.

275/60-15 is what is commonly used on the street and is about 28" tall.  If you see cars at drag strips they fit much taller tires but not sure what they use.

Front, rear, radial or bias ply?  The most common combo is 235 front, 275 rear which is a 26/28 combo. This typically does not have interference issues, provided you get back space dimension that keeps things in tight.

I have run 28" front and 30" rear using drag tires. That means they may not be as wide as many would like on the street. 4" on the front and 10" on the back, and they did not have to deal with driveway angles, curb cuts, or other street issues.

Additionally, if you are running a taller tire, construction becomes important as bias ply tires, high tire pressures, heat, and acceleration can make them grow in diameter. If you are marginally fitting at static load, then the combination above could allow them to grow enough to make contact.

I heard 245/60 up front might be tight.  Not too sure but I know on the first post by Carlwalski and he uses the 245/60-15 up front but has 4.5 back space so you would need to watch out on the inner edge of the tire/rim. 

Not sure if the 265/60 will work on a 7" rim, not saying yes or no.  Try calling a local tire place and I know before when I went to NTB they had a book to show what size tire can be safely mounted on what width rim.  Or you can look on this thread and see who has tried it.

A couple weeks ago I finally bought new BFG T/As (to replace my old, but rarely driven, same tires) for my "street/hwy/cruising" tires... replaced the front 245-60-15 with slightly bigger 255-60-15, and kept the same size rears at 275-60-15... all mounted on my "Performace Superlight" Vintage Minilites 15x8 rims.   The ride is excellent (street/hwy/cruising) and accomodates my stiff competition autocross /road course suspension very well during my "cruising to/from the events" (shows, races, etc).  Also, drove on them in one recent hi-speed road course/autocross event (Gingerman Raceway, SW Mich).. rained all day.. did OK.... looks great as I'm the "Pace Car" for their wheel-to-wheel road races!

I've also just acquired set of 16x8 minilte rims (Wheel Vintiques) with new BFG G-Force Comp-2 tires (255-50-16 front/rear).  I'll use this setup for road course lapping sessions and probably, as well, for the "competition hi-speed road course autocross" championship series events that I'm hoping/planning to get active in again, starting 2014 (~5-6 events for the typical series)....  www.mcscc.org (http://www.mcscc.org) (WIS, ILL, MICH, IN).   I intend to simply drive to/from these road course events on these G-Force Comp-2 tires.  (I haven't yet mounted these 16x8s onto the car... I'll post pics when I do.)

Eventually, I may get another set of Hoosier A6 competition (DOT-approved) autocross tires (they have 40 tread wear rating and stick like glue)... either 255-50-16 for th 16x8 rims, or else 275-45-16 for my lt-wt 16x10 rims.  These tires would have to be trailered (small tow-behind utility trailer or full-size car trailer).   The Hoosiers are the ultimate DOT tire for competition purposes, as well as allowed in the class that I'll compete in.  Just a matter of $$$ for me.

The idea of 200 tread wear tires is also on my mind, but as I have 2-sets of 16" rims (8" and 10"), unfortuantely, there aren't many/any offerings of 200 tread wear tires out there that'll suite my needs with these rims.  I wish, at least, if the newly introduced BFG "RIVAL" tires (having 200 tread wear) would offer them in a decent 16" size, such as at least 255-50-16... those could be driven to/from the events.   The 200 tw rating has become somewhat of a more common "club/class" tire spec.

A 245/60/15 on a 15x7 with 4.25" of bs should fit just fine up front, I've got 275/40/17's up front on 17x9's with 5 bs and the 245/60/15 with that backspace should leave room all the way around compared to mine.

The 265/60/15 should be mounted on a 7.5" wide rim as far as I can see. You can do it, but some shops might not not like it. And you'll end up with some extra sidewall bulge, which will not help handling. I'd find a set of 15x8's and just run the 275/60/15's that you want to.

Well, since I have 4 15x7 rallye rims I'm going to use 255 60 15 on rear. I just can't decide 235's or 245's up front. I saw pictures of 245's, but I would like to see some pictures if possible of 70 challenger with 235 60 15 up front. Lots of older pictures from the beginning of this post don't show. So if any one can post a picture of a 70 challenger with the 235 I would greatly appreciate it.
Maybe 245 all the way around.  Man never thought picking tires would be the most difficult part of the resto. LOL    :bigsmile:

I thought I was going to be first. Oh well, they look great and I'm now in good company. Just got them on Friday night. One of my rear lugs cross threaded coming off and I broke a stud. Not good with a show Saturday morning. Had to find and replace it that night. Got it done.

These are 17x8 with 245-40-17 on the front and 18x9.5 with 275-40-18 on the rear. I can get the back spacing if you like. The right rear rubs just slightly (with a full load of passengers) but I'll be rolling the lip to fix that. Should be good after that.


Are those wheels from E-T Wheels (the LT-III)?

I've been looking at these for a while (trying to save up)...  love the look.   I see some Rotas that look similar but seem really cheap.
I'd be curious about the back spacing if your setup is stock. 

Thank you
Alan

Yeah, they're ET wheels. I looked for my receipt that had the backspacing details and couldn't find it. I've contacted the company again to see if I can get another copy. I'll update when I have the details.

Yes, it's a stock setup. I still need to roll the lip a bit more on the one side. I've done it some and it doesn't rub nearly as much but needs to be done more.

When I bought the wheels, I called and had them help me get the right measurements. They helped a lot and did a great job.

I was able to get a copy of my original receipt from the company.

Front 17x8 - 4.75" BS. Probably could have gone with 4 1/2"
Rear 18x9.5 - 5.125" BS

Well here's my 2 worth. I have been messing with MOPARs for 37 years. I've polished quite the pile of rusty buckets into shiny new pennies.
So I must chime in on the whole 255/60/15 front and 275/60/15 rear scenario. It's too much. The ideal tire size is 245/60/15 front and 255/60/15 rear on 15 x 7's for an E-Body. This combo is a perfect fit for both Cuda and Challengers. The 275 are just too tall for the rear and 255 cut it close on the fenders. If you go to 15 X 8, then the 275 will fit better , but the trim rings will fall short. It will be obvious that they are bigger than 7's. Look at the OP Carlwalski's car. you can see the gap in the rear wheels where the trim rings fall short to the center.
Step off my soapbox.........

That being said anything other than a nice stock look, then go with whatever you like. If your trying to keep it stock looking then stay with the sizes I mentioned..

Hey Lotsspins.. T/Anks for your 2cents... this is what its all about.   Perhaps you don't know, but my T/A has the fender lips tucked in/flushed and still appear stock... too bad the factory didn'tmake them like that.  AND... those mods were done to accomodate 275-45-16 Hoosier DOT race tires mounted on my 16x10 lt-wt rims for serious competition autocross/road racing events... has proved highly succesful (remeber the saying : "TYRES win races"...

Anyway, even with the lowered body height, the "street/hwy" 255-60-15 fronts and 275-60-15 rears fit AOK...  both are mounted on 15x8 vintage mini-lite rims (actually, they kinda look small ... just not fully wide enough to me with the opened lips, as compared to the race tires).... the 245-60-15 fronts were too small for my car.... but.. they are OK.

I have absolutely no fender lip interference with the 255-60-15 fronts or 275-60-15 rears.   The taller sidewalls helps with the ride comfort;  my suspension is fully modified for a nice flat (and stiff) ride through any/all corners... espically driving on the hwys going through fast curves, entry/exit ramps, etc... a pure joy to drive!

The 275-60-15 rears are a bit tall but they fit nicely inside the rear lowered height... and.. the taller diamter helps drop the hwy rpms a little (have a 3.23 gear, as well as optional 3.55 and 3.91.... all behind my 727).

Let's see.. I've been playing with different e-body tires sizes and rims since 1975...   no problems with 245-60-15, 245-50-15, 275-60-15, 255-60-15 (all on either 7 or 8 wide rims); 255-50-16 (on 16x8 or 16x10 rims), 275-45-16 (on 16x10 rims)... all front and rear.... I like big wide tires filling my wheel wells!

T/Anks for the compliments... I've got hundreds of pics of John Sandberg's SCCA Solo/autocross C/Prepared AAR... he and I met racing in 1975 (we had each recently bought our cars that same year) and became best friends...  we'd race together at lots of events (SCCA/related autocross) and were, hoensetly, always the two most popular cars there amongst typical 100-200 cars for local events.. and also the major Regional/National events.

John's son Sean has a 73 Challenger (red with white interior), 440-6, 4 spd, 3.91, 17x9 rims, 275-40-17 front, 285-40-17 rear, 4-whl disc brakes, T/A Fast Ratio p/steering,  Koni fully-adjustable Red shocks, de-arched SS rear leafs, 1.24" diameter torsion bars, all fiberglass front end, 1.25" front and 1" rear sway bars..... overall, the suspension came from the race AAR of his dad's car..... very similar to my suspension.   We're doing some occasional hi-speed track/lapping events.

Yeah I may pick up some Team 3, 17"ers at some point because I think those are most representative of the originals. I just wanted to point out that original, genuine Minilites from England are still available if you are willing to stick with 15" tires. I had them price a set for me once and they are around $1200, for two 15x8 and two 15x10 with custom backspace, built, boxed, shipped to my door.

Post by: Scotts70cuda on January 21, 2014 - 07:54:54 pm
hello,

maybe this is good time to ask for help in setting up my wheels and tires for my 70 cuda.  The car didn't come with any wheels/tires and the car is in the body shop.  So I would hate to wing it.  I want to use a steel wheel and have it painted the body color with the correct center cap.  I would like to use a 15' wheel and the widest tire I can of course : ) It has a factory dana rear if that makes a difference.  Any guidance or opinions would be greatly appreciated. 
Title: Re: E-Body Tire Combos
Post by: Mopar Mitch on January 22, 2014 - 02:53:16 pm
You want to try best to keep the factory centerline of the wheel/tire as factory located.  Here's the specs to follow:

factory 7" wide = 4" backspace
8" wide requires 4.5" bs
8.5" wide requires 4.75 bs
9" wide requires 5" bs
9.5" wide requires 5.25" bs
10" wide requires 5" bs
etc.

Reducing these dimensions will push the wheel/tire progressively OUT towards the fender (lips and wheel well.)  In contrast, increasing these dimensions will bring the wheel/tire IN towards the frame rails and rear leaf springs.

Your tire diameter will be a concern... keeping relatively low profile tires allows more outer fender clearance (lips front/rear, and wheel well in the rear more-so).  You'll have to decide if you're willing to, at least, tuck in the fender lips... the rears will likely need it more that the fronts... consider stiffening your suspension (torsion bars, leafs, etc) to reduce excessive suspension compression, as well as the body leaning under extreme cornering.

With easy-select 8" rims, or even narrower 7", having the above bs, you should be able to safely run 245-60-15 fronts (and even 255-60-15 fronts), as well as easily run 245-60, 255-60 AND easily 275-60-15s in the rear... all without tucking the lips.. except the rears for the 275-60-15 may like you better IF you'd tuck those rear lips a little.

Anyone tried Bassett wheels?

I'm liking the 15" D-HOLE LIGHTWEIGHT WHEELS. I want to stay with 15" and around 60 profile for looks. The 8" rim should take up to 265 - yes?

Would the 10" rim fit under the stock rear without mods and if so what max size tire would fit do you think?

Do you know anyone with these rims? Cant find any pics so far, let alone max tire sizes on these rims.  :dunno:

I have typically stick with the tire width equals tread width approach, but that does give you some latitude for section width differences.

In my experience,  a 10" rim will not fit in the stock wells with out springs being moved, or using such a skinny tire it look silly.

Also, Bassets are not d.o.t. approved and they have 45* lug seats instead of the traditional 60* seats, so they require matching lug nuts.

I have similar wheels from Aero on my challenger. Look through some earlier threads and you should be able to find pictures, however mine are chrome.

Wow.....finally... just went trough the entire 49 pages and it took me forever ;)

But i have a another question since i didn't find what im looking for in those 49 pages.

I have a 71 Challenger that is 100% original front and rear (8 3/4)  and i just ordered Hotchkis Tuned Shocks, 1.5 S.P.S front and rear
and Hotchkis Swaybar Set front and rear and Wilwood front disck brakes and Magnum Force 2" drop spindle.

Im am looking to buy some wheels and have set my eyes on AR TTs M
From what i have read in this i thread i think i can run 17x9,5 in the back with a 275/4017 tire but i not sure what BS i have to get... maybe 5.25 BS?
im not sure on the front with the 2" drop spindle, i think i can run a 17x8 with 4.5 BS?

What do you guys think, i want to fill the wheel wells as much as i can without rubbing.

I am having tire woes myself. Building a 71 Challenger Convert with a 6.4 HEMI and a NAG1. I have the street lynx rear suspension and the alterktion front.
Tires and wheels are the problem at this point. Looks like I'm going with a Foose Knuckle F237 with 18 X 10 Rear with 285/40-18 and 5.5 backspace.
The front is 18X8 with 245/40-18 and 5.5 backspace. This is what Reiley motorsports says will fit. I think the front backspacing is going to hit the front frame on a
tight turn. But they say the tires will hit the fender if I bring them out. By our measurements, it will clear by an easy 2" with a 4.5 backspace. Anyone have anything close to this or have a suggestions. Reiley say keep the tire height on front at 26" max and rear at 27" max. to keep the car setting lower.  :banghead:
I like seeing on the rear about an inch of tire above the wheel to the quarter lip.
Even any pics of cars with 18" and reiley suspension??? any ideas????

I don't think you'll hit the frame in the front. I'll qualify that by saying I have the standard Mopar front suspension. But, I know that the RMS kit moves the spindles out (widens the track). I run 275/40/17's with 5" of backspace on 17x9's in the front, and don't have any rubbing on the frame. With the narrower tires and increased track from the RMS kit, I don't think the 5.5" backspace will be an issue. Even if it is close, you could add a small spacer to add clearance. If you go with too little backspace and it hits the fenders, there's nothing you can do.

Those 17" Summit rally rims are cool looking and the prices are good/reasonably affordable.  Someday i maight purchase a set of them i 9" width for front and rear and easily run ~275-40-17 tires for competition solo/road course lapping events.. with 200 treadwear tires.   BUT, I have to let all of you know my own experience with this style rally rim.. steel (OE).. they actually tend to flex in the center radius, right were the OD of the center cap is.. and.. under severe cornering G-forces (with sticky tires, such as Hoosiers, that center section has been known to frcture and break!... leaving the center small section (center cap and broken remains of the rim) still bolted to the hub while the rest of the wheel rolls away with likely damage to your fender.    So... beware!

Only got them out on the road for a few miles so not much to say but the wheel tire comb sure track nice.

Quick ratio pitman and idler, plus complete PST 11/16 tie rods. Not pictured are the ball joints and all new bushings etc. Rebuilt LCAs from Norm's Speed Shop.

Keith,

I have 18x9 with 5.5" of backspacing with a 275/35/18 on the front of my AlterKation equipped Cuda.  Even with the stock suspension for some reason my tires would always hit the fenders if I went over a 245 in the front, so I did have to cut my fenders some on the bottom front of the fender arch to make them clear.  You might not have the problem, but I would recommend you mock up your wheel and tire combo before final paint.

No issue with the tires rubbing the frame or anything especially given the crappy turning radius of the AlterKation!   :lol:

After I fixed my saggy rear by adding leafs I discovered that the 225/70R15 for the front are just a wee bit too large (diameter-wise). So I scaled back and am now running 225/60R15 in the front (on 7" rims) and 275/60R15 in the back (on 8" rims). It's on the high (and wide for the 275) side for me but I like it! Much much better than the 205/60R14 before with the saggy back. Now if only Summit delivers those center caps...  :jumping:

Still???


A nice day to get the Cuda out finally.
Firestone Wide Oval Indy 500 on Year One Rallye Wheels Front 245/45R17 17"x8" 4.5" BS, Rear 275/40R17 17"x9" 4.5" BS
Both front and rear tires are 25.7" tall. Still sitting on old suspension. Every corner is a different height right now... :screwy:
That should change when I get all the new suspension on. Torsion Bars, ESPO Leafs... :working:

So I'm looking at new rims now. I'm going 15 inch. Problem is the rims I want  don't come in the right backspacing. 15 x 8 in the rears calls for 4 1/2 inch backspace. The vision rims I'm looking at are 4.44 inch backspace. Fronts are 15 x 7 4 1/4  inch backspace. The visions are 4.17 inch backspace. With a 275/60 15 tire in the rear I'm worried that it won't fit properly. Any ideas?

Those aren't off by that much, I'm willing to bet they'll work.  I assume you meant 275/60R15's.  I would still take careful measurements as every car is different.

Adjust those torsion bars.  They make a big difference of height on all four corners; not just the front.

I ran a 15x8 with 4.75 back space and a 295 tire. It was about .5" to the front segment of the leaf spring and 1.25" to the opening lip, but they fit. I would think a 4.44 back space with a 275 would fit fine.

Compare it against what you have now. What is your current rim spacing and tire size? How much bigger is 275 and what is the change in spacing? That should give you a visual of the change After all, we are only talking about a 1/16 of an inch difference from the ideal 4.5 spacing.

My rims  are 14 x7  3.5 backspace. 215 70r 14. Big difference from a 275 14
Title: Re: E-Body Tire Combos
Post by: HP2 on May 22, 2014 - 12:37:22 am
215/70r14 is 26.9" tall and 8.7" wide. 275/60r15 is 28" tall and 11" wide . So your 1/2" taller from center. No big deal. You are also 1.15" wider per side, but call it 1 1/8" for simple measurements and fudge factor. Probably no big deal here either, but lets check.

With a 4" backspace rim you would have the same zero offset on a 15x8 as your 14x7 with 3.5" backspace and relating the above measurements would be simple tape exercise of adding in the extra dimensions against your current combo.

However, your chosen rim has 4.44" backspace which means it is .44 offset from zero. So you have to add .44 to the 1.15 for 1.59" That means you new combo will put the tire sidewall 1 1/2" closer to the leaf spring than your current combo. On the outside, we take out 1.15 wider tire and subtract .44 and get .71. That means your new combo will be just shy of 3/4" wider towards the wheel opening side than your current combo. So you can check: if you currently have more than 1.5" from the sidewall to the rear segment of the spring pack, (don't forget E body springs are splayed wider in back),  then your new combo will fit. Some on the outside, if you have more than 3/4" to the fender lip, it fits.

Now that you know how these dimensions compare, the change to a 4.5" backspace rim would add an extra .06 or 1/16" measurement to the spring side and subtract the same 1/16" from the fender side and you can see the difference between the 4.5 rim and the 4.44 rim.

Or you find a friend with the same combo, borrow his rim, and test fit it, have a beer, shoot the breeze.

Wonder would the new 18" charger wheels fit on a Challenger?

I have the new 20" chrome challenger wheels that came off a 09 RT (got for $500 and car had  miels on it). They fit fine on my B-BODY (68 gtx), tho the car sits too high in the front.  I haven't adjusted torsion bars and I'm planning on buying big Willwood brakes that come w/drop spindles anyway. but haven't tried them on the cuda yet.  But, I plan to and will let u know.  I bought them when I didn't have cuda yet, and needed bigger wheels since the brake kit im getting requires 17' rims or bigger.  Now I.d rather have on cuda I think, a long as will fit/look ok. will keep u posted. PS- I tried to post some pics but the file sizes were all too large.  I can send to u via email if u like.  I can be emailed at joe1978c@yahoo.com if u wud like to c pics on b-body for now

Hello all... I am sure this topic has been covered at some point or another however I cannot find a thread that discusses my exact trouble.  I am back to work on my 72 Cuda and am down to dealing with rear wheel sizes.  I have a 8 3/4 sure grip with a SSBC rear disk conversion bolted to it.  The wheels that are on the car now are custom 18" x 9" Torque thrust II with a 4.5 inch backspace.  The problem is with the SSBC disks the wheels are pushed out about an inch so when the car squats the tires get into the quarters.  I have a Percys wheel fitment device and it says I will need a 5.5 inch backspace.  I want to stick with a 18x9 or 18x10 inch wheel but need to verify the backspacing.

Has anyone else seen this problem when using the SSBC conversion?  What backspacing did you go with?

9" wheel mostly have BS of 5" and works well assuming without excessive tire sidewall bulge. 10" wide wheel should carefully check clearance to spring. Best is to just measure before ordering wheels.

Finally bought some tires to put on the wheels I bought a few months ago.

Summit Legends with Nitto 555 Extremes..

Fronts are 17x8 with 4.5" b.s. and 245/45-17s.   Rears are 17x9 with 5.0 b.s. with 255/50-17s.  I was going to use 275's on the rear but after doing the hotchkis suspension, the car was barely clearing my four post lift when driving on and off so I wanted to gain a little height and the 255's are 27.1" tall.  In the end, I lifted front and rear about 3/4" from where it originally sat after installing the Hotchkis parts.

I was pleased with the quality of the Legends and very little weight was used to balance them when the tires were mounted.  Only thing I don't like is that front and rear, I only have about 0.6" thread engagement on the studs.

Thanks to 72bluNblu for the consulting!  :)

I used Mr. Gasket #4311 studs on my stock axles. They're 2 7/8" long, but it would be pretty easy to cut them down to the length that you want. That would take care of the rear anyway. In the front I have ~.75" of thread engagement, which is at the high end of the recommended 1 to 1.5x diameter. With .60" you're probably ok, but I'd want more too.

These are what I've used in the past on the stock rear axles
http://www.summitracing.com/parts/mrg-4311 (http://www.summitracing.com/parts/mrg-4311)

These should work for the front disks if all the diameters I looked up are right. Again, they're long, but you can cut them down. If you had a 1/2-20 die that would be ideal, but you can actually dress the threads with a small file if you don't.

thanks for the info! :)

I don't want to use open end lug nuts so I will have to cut them down.  I got confused Saturday because I kept finding  different  knurl diameters.  year one shows the rears to be 0.673 and the Mr. Gasket are 0.665 if I recall correctly while they show ARPs as being 0.680....not much difference but it makes me wonder.

I am going to swap the front rotors for the larger ones since I have the caliper brackets and I did not look to see if they are shown to be the same as the smaller e-body rotors....

I am not driving the car hard...just been happy to drive it.  Still have a number of things I need to do to it...not including air conditioning which is also on the list.

Running factory 14 inch road wheels on a 73 challenger with 245/60R14 on all 4 corners.  14 inch tires are getting hard to find unless I want a goodrich or cooper.  Those are not my favorite two choices.  Thinking about stepping up to a 15 or larger road wheel if I can find them and comparable raised white letter tires to keep a stock look.  Any ideas as to what and where to find them?  below is a pic of the rims i have. So I would like to get the same style wheel.

The Hotchkis rear leaf has less arch in it to reduce the roll center.  The lower the body sits to the axle, the less leverage it has to roll side to side.  I believe they claim an inch lowered compared to stock but that depends on what springs are on the back of the car at the moment and their condition.  I don't recall exactly but I am pretty sure the front spring hangers that come with the springs have the front spring eye mounting holes in a bit different place.

In the front, I used 1.03" torsion bars which allows me to put the front of the car where I want it without much fear of bottoming out on a good dip.  I may come down a slight amount in the front because it was set with shorter front tires.

I have not installed the rear sway bar yet but the car handles light years better than it did.  It has the Hotchkis/Ridetech version of the Bilstein on both ends.  I see they are now using a shock that is claimed to be even better.

In the front, I used 1.03" torsion bars which allows me to put the front of the car where I want it without much fear of bottoming out on a good dip.  I may come down a slight amount in the front because it was set with shorter front tires.

I have not installed the rear sway bar yet but the car handles light years better than it did.  It has the Hotchkis/Ridetech version of the Bilstein on both ends.  I see they are now using a shock that is claimed to be even better.


Great, thanks for that info!  Thats pretty close to the height I would want so its good to know the what the hotchkis looks like with your wheel/tire setup.  Maybe you've posted a thread with details of your setup and I missed it but did you make any other changes up front aside from the torsion bars?

Hotchkis adjustable struts, poly bushings in the lower arms, tubular upper arms, new ball joints, the larger tie rod ends/sleeves from the big cars, steering arm, idler arm, cross link-all Moog stuff.

Hotchkis sway bars

When I repaired the frame rails, I sent the steering box to Firm Feel for rebuild to Stage 2 specs.  Should have gone Stage 3 for a bit more steering effort but I will shim the bypass valve in the steering pump for a bit more. 

While the K member was out, I welded up the seams and added some gussets to the steering box mounts to minimize any steering box movement while corning.


If you read 72bluNblu's thread on his suspension build up, you will learn a lot about how to build a good handling car using economical parts.  Brad and HP2 are two more guys that know their stuff.

These are what I'd like to put on my '70 Barracuda. The rear springs have been moved in on a Dana 60.
I believe I can have at least a 325x50x18 rear tire. Fronts would be 255x8x17. Chrome (wife says) Torque Thrust 425's. What say you? Greg.

Fronts are easy, 255/45/17's will be fine on a 17x8, backspace should be between 4.5" to 5", 4.75" is probably ideal. That tire size is pretty readily available.

Rears are going to be a problem. Tires in that size (325/50/18) simply don't exist, at least not for cars. But you should be able to fit a 325mm wide tire in the stock wheel tubs. I have 275/40/17's on my car, and have over 1" to the quarters and springs. I only have a 1" relocation kit, but my springs are almost even with the inner wheel tub so the bigger relocation doesn't but you much extra space. I think max would probably be a 335mm wide tire, that would probably require rolling the quarter lip for clearance. There are a few 335/30/18's out there still available, that's still a 26" tall tire. Selection in that size is pretty limited though. It's amazing how much selection for the 17 and 18" rims has dried up recently, everything is going to even bigger rims.

If you have an E-body width Dana, an 18x12 will need about 7.3" of backspace (20mm offset).

Ok wheel and tire experts! I'm looking at some 18s, 18x10 +25mm offset, and 18x8.5 +35mm offset. Back tires are 295/35 and fronts are 245/40.  Completely stock suspension right now, will they fit?

The tire sizes are possible with the stock suspension, but your offsets are wrong.

In the rear, to get an 18x10 with a 295/35/18 with the stock spring location and E-body 8 3/4 you're going to need an 18x10 with roughly 5 to 10mm of offset. A 295/35/18 will pretty much be shoehorned in there with the stock spring location, but it should fit if your rear axle is fairly well centered. If you're not opposed to rolling the quarter lip a little it shouldn't be a problem. Your other option would be to install a Dr. Diff 1" spring/shackle offset, in which case the 18x10's with a 35mm offset would fit just fine.

In the front a 245/40/18 on an 18x8.5 is pretty small compared to the space available (I run 275/40/17's on a 17x9 with 0 offset), but a 35mm offset will put you into the frame. If you wanted, you could run that set up with a 1" spacer adaptor. Otherwise, I'd be looking for something with an offset closer to 0mm. You could probably run as much as 15mm offset with an 18x8.5" and a 245/40/18, but it would look pretty goofy. You'd have a ton of room to the fender.

So, you can make those rims fit with those tires, but you'd need a 1" spring relocation in the back and a 1" spacer in the front.

255 is as big as you can probably go on a 7 inch rim, because remember, 7 inches is about 178mm, so that means you will have about 40mm of rubber bulging out each side of the rim.
It might look a little meaty.
I have 245 rubber on my front 8inch rims, and I think it fits about perfect

Hello, question, i have read all 53 pages too bad some pics are gone, but they where really old.
I decide to go with the boss 338 rims. But I did not see if anybody ever did this tire size on them for the rear:

front : 18 x 8 , Tire 245/45/18 This was done by an other member
Rear : 18 x 9.5, Tire 295/45/18, I have not see anybody put this except an question on it.

I want to go as wide as possible on the rear and going for the staggered look.

I'm currently running 215/65/17 on 7' rims all around. some little rubbing on the front on the chassis.

What we have measured our self with an tire measuring tool is this :
for 18 this would fit :

285 50 r18, 18 x 9.5, Back spacing 5.5
215 60 r 18, 18 x 7,Backspacing 5

But 285/50/18 as an tire doesn't exists. and the boss 338 18' doesn't come in 18x7. I assume my car is stock, no clue on the rear.

Any advice is highly appreciate.
And for the picture lovers how it looks now and yes those are hub caps from dodge ram truck, they told me if you are wondering.

You need to state what offsets/backspacing those Boss 338s come in for us to chime in with a solution.


The general consensus is...9" is all you can go in the back w/o having to do an offset shackle kit.  With a Dr Diff 1" shackle kit on a stock e-body rear, you can go up to a 10" rear with 6" of backspacing.

If you only have a 9.5" rear, then 5.5" of BS is all u need.


Use a tire calculator to compute BS if all you have is offset.

Front's fine.  It may hit some suspension if you go too wide a tire, but you can always add a spacer. 

Rear, it's going to be tight.  With only 5" of BS, don't think you'll have much room on the outside even if you roll your fender lip some.

I would look for another wheel.  My $0.02.

Thats obviously skinny compared to what most are running today, but I dont think it will be too tall. Probably tight though. May depend on what if any modifications have been made to your car. So many have been modified over the years.
Those are very nice wheels though. Worst case scenario you can go with the 245/45s  :bigsmile:

Tired of seeing BFG's on every car too, so I went with M/T's. 255/60's on 15x8's and 235/60's on 15x7's. Love the look, but the repro caps are pure junk. They pop off sitting in the garage. Located a set of cop caps and a set of redline caps as well, should be here next week sometime.

235/60 easily. 255/60 maybe if backspace is spot on and you don't have any weird tolerance stack up in the sheetmetal assy and your car isn't lowered.

All, the results of the question I asked in October about Boss 338 18 x 8 front and 18 x 9.5 rear.
Well We all have some stubborn in us, So I choose for the Combo all though "Ragtop" mention it would be to close.
It fitted, drivers side without any problems sufficient space. Passenger in the back unfortunate it was like an half inch to wide. Thank god I have airshocks in the back so by have them completely filled, that solved the immediate problem. We ended up modifying the lip in order to make sure I had sufficient clearance. And to have it equal we modified the lip on both side's.
See the pic's for the final result.
If you want to go with combo choose an different offset of 5.5 and not 5.

Post by: mcemond on January 08, 2015 - 02:00:34 pm
I just realized this may be off topic. Feel free to remove it if so...

I have kind of a weird question regarding rallye wheels and trim rings as I attempt to resolve... "front spacing" (I've never heard the term before, but sounds appropriate  ;) ) to make wheels of different widths look identical.

The set up I am looking at (after much research here) is:

71 cuda, stock suspension - no rolled fenders or spring re-positioning
Wilwood front discs (15" minimum wheel, very minimal offset) stock drums on rear
OEM "Look" with today's wider footprint and a slight rake
Rear: 15 x 8 Rallye (backspace see question) with either 275/60-15 or 255/60-15 (still deciding if I want that extra .8" of tread width)
Front: 15 x 7 Rallye with 235/60-15

So what I was researching was, the wider the wheel, the more the trim ring begins to obscure the design holes in the rallye  assuming you are keeping the same back spacing on all 4 corners. Also, by staggering the widths you get a noticeable difference in this obscuring from front to back. That "OEM look" was achieved with pretty skinny wheels all at the same width. So I was thinking, what if you increased the back spacing on the (wider) rear set by an inch (or whatever) and use an equally measured spacer to compensate basically making the "front spacing" if there is such a term, equal on all 4 wheels. Then all 4 would theoretically look identical from the outside of the wheel. So far all I've found for back spacing in an 'off the rack' 8" wide rallye is wheels vintique with 4.5 or 4 5/8" for Mopar Factory. So for a wheels vintique i'd be looking at a 5.25" BS in an 8" wheel to match the front depth of their 7" wide wheel (4.25" BS) and so on. Apologies if I missed reference to other Rallye options earlier in this thread. Its a long thread and I tried to read most of it.

So if the above sounds correct I figured I had a couple options:
1. Custom wheels (I hear Stockton is no longer in business) but no thanks - sounds too expensive
2. Run all 4 corners on 15 x 7's
3. Live with the trim ring depth difference.
4. Go with an aluminum wheel that mimics the style.
5. Or go with a chromed rallye and paint the centers silver. Has anyone had a try at that? I wonder how it would look? This idea is growing on me.
6. OR... maybe someone has already dealt with this scenario here and has figured it out/ found wheels  (or maybe i'm just being too crazy about such an odd thing )

Anyway, thanks for reading.

1. This is a possibility. There are a few places out there that could take a 15x8 4.5" backspace, cut the hub out and move it over that 1" to achieve the same front space as a 15x7.
2. Most economical answer.
3. I haven't seen a decent looking aluminum copy of the rallye wheel yet.
5. Not sure why you would do that unless you found chrome wheels with the exact spacing you want. I'd be worried about longevity of this approach, but it can be done.
6. We all have our quirks.

I've tried search ... and reading pages .... lol ... but ... want to verify something.

For 1970 Challenger (stock suspension and rear end config) I am looking for something in 17" that will fit with no issues nor any customization.

I want to try to retain stock look ... but better rubber ... so:  17" X 8" cast aluminum "Mopar Rallye" wheel YearOne (https://www.yearone.com/Product/challenger-cuda/mrw178slvs (https://www.yearone.com/Product/challenger-cuda/mrw178slvs))

They state "Original fitment test done with 245/45-17 BF Goodrich G-Force T/A-KDW tires."

Can anyone help confirm these rim with tire specs above fit no problem?

I understand you need different lug nuts .. that's fine.

Or if anyone knows of any other brand that are Mopar Rallye style in 17in   ...  :thumbsup:

Thanks all ... awesome site for great info!

Trying to see if we can hit Carlisle this year as well ... never been ... would be awesome!

The tire sizes are possible with the stock suspension, but your offsets are wrong.

In the rear, to get an 18x10 with a 295/35/18 with the stock spring location and E-body 8 3/4 you're going to need an 18x10 with roughly 5 to 10mm of offset. A 295/35/18 will pretty much be shoehorned in there with the stock spring location, but it should fit if your rear axle is fairly well centered. If you're not opposed to rolling the quarter lip a little it shouldn't be a problem. Your other option would be to install a Dr. Diff 1" spring/shackle offset, in which case the 18x10's with a 35mm offset would fit just fine.

In the front a 245/40/18 on an 18x8.5 is pretty small compared to the space available (I run 275/40/17's on a 17x9 with 0 offset), but a 35mm offset will put you into the frame. If you wanted, you could run that set up with a 1" spacer adaptor. Otherwise, I'd be looking for something with an offset closer to 0mm. You could probably run as much as 15mm offset with an 18x8.5" and a 245/40/18, but it would look pretty goofy. You'd have a ton of room to the fender.

So, you can make those rims fit with those tires, but you'd need a 1" spring relocation in the back and a 1" spacer in the front.

This answer from a couple pages back helped answer my first question about an 18x10 in the rear with stock suspension, however, if I were crazy enough to try and stuff an 18x10 in the front (it can be done with perfect backspacing), where would you recommend starting off with offset/backspacing?

Also, what is everyone's opinion of wheel spacers? Seems like some folks are all for them, while others hate them. Custom wheels just arent in the cards for me right now.

For a 10" rim you'll need a 5.5" bs, but it may become tight with leaf spring and tie-rod, etc.... but you could make it 5.25" (if someone would do that for you) and then consider flushing you lips.   I have 16x10 rims, f/r, with 5" bs, 275-45-16 tires (Hoosiers A6).... and the lips are flushed and slightly pulled... they appear stock... functional and awesome!

Keith,

I have 18x9 with 5.5" of backspacing with a 275/35/18 on the front of my AlterKation equipped Cuda.  Even with the stock suspension for some reason my tires would always hit the fenders if I went over a 245 in the front, so I did have to cut my fenders some on the bottom front of the fender arch to make them clear.  You might not have the problem, but I would recommend you mock up your wheel and tire combo before final paint.

No issue with the tires rubbing the frame or anything especially given the crappy turning radius of the AlterKation!   :lol:

Okay wheel gurus, I have a question. The wheels I want for my cuda only come in an 18x9. Is it going to be possible to run 305/40 tires on the rear, or will the wheels be too narrow? Also, I would also like to know the answer from the post above mine.

No, you're not going to be able to run 305's on a 9" rim. A 18x9 is pretty much maxed out with a 275. I have 295/35/18's on a set of 18x10's on my Duster, but again, those are pretty close maxed out for that size rim. To run a 305 you need at minimum a 10" wide rim, and really you should plan on an 11" wide rim for that size tire.

The post above yours? About the 20x9's? Sure, they should fit, or at least be close enough for a small spacer. A 9" wide rim on an E-body in the front needs about 5" to 5.5" of backspace, ideal is probably about 5.25". But, you're going to have to run an awfully small sidewall to make that work. I wouldn't run anything taller than 26.5" in the front. On a 20x9 that's like a 255/30/20 or maybe a 275/30/20 at the most. But once you go past about 26" tall you'll probably need to limit backspace to around 5.25" or so, otherwise the tires will rub the frame at full lock.

Post by: turbo224 on March 26, 2015 - 06:47:26 pm
So I knew the rear end of my car had been modified by the previous owner, and I finally got around to figuring it out what's been done. I used measurements from my brothers stock 70 T/A to compare to my car. My axle is 2" narrower than his, so I assume I have a B body rear end. I also know my car has an offset shackle kit. My leaf springs are 3.5" narrower than his, so I assume each side has been moved in 1.75". Sound correct?

According to others in this thread, I should be able to fit a 305 series tire on the back of my car. I was looking for a 305/45/18 or a 305/40/18, but there doesn't seem to be a lot of options out there for a 305 and an 18" rim. Am I missing something?
Title: Re: E-Body Tire Combos
Post by: HP2 on March 27, 2015 - 09:32:08 am
With that set up, you may be able to run up to a 325 without any major problems, but wheel spacing and overall height are still factors. I'm running 26x12x15 under my Challenger with a B body rear and 1" inboard springs and I have plenty of room with a 10" wide wheel and 5" backspace.

Looking through Summit's tire selection, they list over 60 tires in the 300-325 range in 18" diameters with varying sidewall aspect ratios with the most populated size being 325/65-18. Some of these dedicated race tires and a lot of them are truck tires too. You'll have to sort through them all and see if you can find a tread pattern and speed rating compatible with what you want. IMO, a T rated truck tires with an all season tread will work just fine on most cruisers and give you 50 series sidewalls. If you really want to push it performance wise, they you may have to drop down to 30/35 aspect ratios to keep overall height down.

Uh, a 325/65/18 is 34" tall.  :22yikes: Good for a 4x4, not so much for a musclecar. I mean, our '71 F100 4x4 needed a 4" lift to run a 35" tall tire. Warning, non mopar content

(http://img.photobucket.com/albums/v513/Dark04/F100/71F100.jpg)

Even a 325/50/18 would be 30.7" tall. That would probably require quarter surgery, or at least wheel tub surgery.

325/40/18 would be 28" tall, and that would be about the tallest I'd want to go unless we're talking a drag car with giant slicks. Realistically, for a street car you'd want to be at 325/35/18 (26.9"). A 325/30/18 is at 25.7", which isn't bad but a smidge short for the rear. On the other hand, if its autoX or road race you want to do it's better to have all the tires the same height, and that 325/30/18 would be the same height as a set of 275/35/18's up front, which is about as wide as you can go without rolling and pushing the fenders.

Personally, I think about a 26" tall tire is where you want to be for the street or handling. If you're doing street/strip or going for that '70's musclecar look anything up to about 28" will work great. Much taller than that and it's probably going to require more serious modifications.

Good info, thanks. These will just be street tires, so I'm more concerned with the way they look instead of performance. I have slicks for the track. I've alway run 40 and 45 series tires on my audi, and the sidewalks on those are pretty slim. I would have thought that a 30 or 35 series tire would be razor thin, but maybe I just don't understand how sizing works.

Yeah, I did say most of those are trucks tires.

Unless you going for the early pro stock look, you probably want to stick with 26-28 tall tires. Even 30" is getting pretty tall.

Here is a 295/65x15 BFG drag radial at a hair over 30" tall. These are on 15x8 with 4.5" backspace. Tight, but possible. This was with a 26" tall front tire. You'd need a 28" front tire to make this look work.

I've alway run 40 and 45 series tires on my audi, and the sidewalks on those are pretty slim. I would have thought that a 30 or 35 series tire would be razor thin, but maybe I just don't understand how sizing works.

For reference, the "series" is the height of the tire's sidewall, but it's listed as a percentage of the width. So, a 35 series means the sidewall height is 35% of the width.

For example-

275/35/18: Width is 275mm, sidewall height is 275mm x .35 = 96.25mm
                 To get the height, you need 2x the sidewall, convert to inches, add the diameter of the rim -   96.25mm x2 = 192.5mm =7.57", 7.57"+18" = 25.57" tall tire

325/35/18: Width is 325mm, sidewall height is 325mm x .35 = 113.75mm
                  Tire height is 113.75mm x2= 227.5mm =8.96",  8.96" +18" = 26.97" tall tire

So, even though those are both the same series tire, they have different sidewall heights and overall tire heights. The wider the tire, the taller the sidewall for a given series. It makes things a little confusing, because you can have 35 series tires that have more sidewall than a 45 series tire, if the 35 series tire is wider. Put another way, if you want to keep the same tire height, the wider you make the tire the smaller you'll need to make the series. A 255/40/18 is 26" tall, but a 325/35/18 is 27" tall. And the math is only an estimate, if you go on TireRack.com they actually list measured heights for the different tires, some are a little different than just the straight math. But usually they're within a tenth of an inch or so. Some tires run a little wider, some a little taller, just depends on make and brand. Just like shoes- A size 10 should always be a size 10, but we all know that sometimes you need a 9.5, and sometimes a 10.5, just depending on the type of shoe and who made it. Same thing.  :2thumbs:

This is gold! Ya learn something new every day. I'm really struggling to find an 18" wheel that I like that comes 10" wide, so I may be going 20" in the rear and 18 up front. I saw a number of cars with this combo at Mopars at the Stripe this weekend and didn't mind the look.

I'm still a a little confused about how back spacing works. Is the lower the number the farther out in the wheel well? I'm looking at a set of 18x9.5 for the rear of my cuda. They have zero offset and 5.25" back spacing. I've read in the thread that 5.5"-6" of back spacing is ideal, does that mean these wheels will need a spacer?

Thanks Turbo224 and Mitch.
Here is a pic from behind, crappy photo sorry.Because I used a B Body diff housing and axles the pinion angle is different to that of the E Body, due to my x pipe behing tucked up very tight, due to the pinion now pointing down a couple of degree's, on braking the balance weight on my tailshaft now tags the top of the X pipe so I need to wedge it to raise the  pinion to give my driveshaft/Xpipe some clearance. ultimately I will probably adjust the spring pads on the housing to get rid of the wedges. By going to the B Body housing and Dr Diff's 1" spring offset kit it gave me some extra clearance for tires.

Mitch, I made those offset links out of 1/2" barstock, just turned each end down to match the origianl links, added about 1/4" in length in the centre section to come back to correct length once offset is done, then simply held them in the bench vice, heated and bent one bend then moved the torch up, heated the other end and bent it straight and I have my offset. they cant rotate due to swaybar length etc, nothing moves left or right, it cant. Took me about an hour tops to do, really easy.
I will be ultimately fitting 18x11 SSR SP3 proffessor wheels on the rear and 18x9 on the front

Sup guys, picked up a set of 14'in ralleys over the winter looking to get some fresh rubber for my 71'. Would like bigger on the back for that jacked up look...can't really decide on a size any suggestions stock rear and suspension

14" rallyes, OEM, maybe 5.5" wide....I think the biggest you can get for those is 235/70.  Those are not going to lend them selves to a classic beefy look.

I'm looking to buy some new wheels/tires.  The car is a 70 Challenger and on the front has FF tubular UCAs + DrDiff 13" w/ Brembo knockoffs and on the rear has DrDiff 11.7" w/ Cobra calipers and XHD springs in the stock location.  I have .99" torsion bars but plan to go to 1"+ in the near future.  Fender/quarter wheel well lips have been rolled.

With a borrowed wheel rite tool, I found that for the rears, a 18x9.5 w/ ~4.75" BS and 275-40s has ~1/2" clearance to springs and quarters.  I'd like to get maybe 285/40s but have not had time to see if that works on the car. 

On the fronts, a 18x9.5 w/ 5.5" BS and 275-35s will fit nicely in the front fenders at ride height and has ~1/2" clearance to the fame at L/R lock.  I have questions about clearances on the front when the suspension is at the extremes.

I've read here in many threads that the rear tire to spring/quarter minimum clearance to aim for is 1/2", some folks have pushed this down to 1/4" or smaller.  What are acceptable clearances to the fender/frame for the front wheels?

At full compression with the LCA jacked up so that the LCA bumper is lifting the car up, I get about 1/4" clearance to the fender at both L/R full lock.  Frame clearance is at 3/8".  Are these acceptable?

At full extension with the UCAs resting on the UCA bumper, the only interference is the struts at full lock when the  wheels are pointed in.  Is this a case to be concerned about?

Ok so I do not like this look but it's ALMOST there....On my 70 Cuda I have this setup:

Front:  17x8 w/245/40 with 4.5 BS
REAR:  18x9 w/285/40 with 5.25 BS

I lowered rear 2" and front 1.5"

And they look like little "doughnuts" on the car. What can I do tire wise to give it more of a bite? I can't return my rims but my buddies at the tire store will work with me on the tires since they have not been ran yet on the car. I want a little more tire I think...any suggestions??

 I really like the way the LT-III wheels looked on Brads70, ntslgl1970, and peterro's cars.  I'm happy to report that Team3 LT-III 18x9.5, 5.5 BS with 275-35 Nitto 555 fit the fronts. The DrDiff stage 4 brakes increase the track by 3/16" per side, I rounded up to 1/4".  The wheels required two spots on the lower portion of the calipers to be filed in order to clear the rims.  You cannot see where it was filed when the wheels are on.

Rears are 18x10 5.25 BS with 285-40 Nitto 555.  Right now I can fit my fingers in between the tire and fender and there's about 5/8" between the tire and leaf spring.  Both front and rear fender lips were previously rolled.

Yesss!
finally heres my setup and pictures. I mounted them today: :bigsmile:
American Racing Torque Thrust IIs with BFG g-force T/As
Front:  17x8" w/4" backspace and 245/45
Rear: 17x9.5"w/4.5" backspace and 275/40
Clearance is great all around

These two tires are roughly the same overall height at 25.7", and though I'd prefer 50s front and rear to fill the wheel wells a little more, and maybe give a slightly softer ride, you cant really find that size in a 17". Not with rubber that I like.
I hope you enjoy the look as much as I do. :cheers:

Post by: whitewatersky on July 27, 2015 - 09:10:50 pm
I thought I posted in here already, but couldnt find it? Anyhow, I took this from my restomodification thread....

I ended up going with 18x10 Cragar 612 series S/S wheels. They are basically the same wheel as the standard S/S wheels except they are all aluminum and polished instead of chromed. They are MUCH lighter than the hybrid design. The fronts are the hybrid design and are 17x8 (4.5 BS - 38lbs a piece) with 255/45/r17s. The rears are 18x10 (5.25 BS - 24lbs a piece) with 285/40/r18. I went with a 68 B-body rear end with Dr. Diff's 1" offset kit. The tires are Nitto 555s and without the relocation kit - they would definitely rub. As it sits right now, they have a little less than 1" clearance between the wheel and the springs and ~.5" between the wheel and the lips. I also lowered the car 1" in the rear via Dr. Diff's relocation kit. After driving it, I would recommend 245 for the front OR an extra 1/4" of backspace. I have minor rubbing issues when turning and hitting bumps, which caused me to raise the front a little - I plan on rolling the front fenders to remedy this issue and lowering it back to where I want it. The rears have no problem whatsoever with the relocation, in fact I have room for a wider tire - I know a 295 will easily fit and I think with perfect backspacing a 315 will even fit. These pics are kind of old as I still didnt have my exhaust hooked up.....

It's PPG single stage EV2. It's a little lighter than the original EV2 paint on some of the parts I have.  I really like this color as it seems to change shade depending on the type and amount of light - sometimes it's a dark reddish orange other times it's a bright, retina searing orange.

Those look good! Glad everything fit ok, the fit was a little conservative but it's always better to have a little extra room than to have interference and have to figure out out how the make things fit after you've already spent a ton on new rims and tires.

I'm currently having wheel woes. I got a set of AR Hopsters with the car and they don't clear good in the front. On a hard turn, if the front drops it will rub the fender lip up in the higher part of the fender. That could end up bending the fender out and causing some damage. Nearest I can figure the wheels are 16 X 8 with a 4" backspacing. Tires are 225-55-16.
I am looking at a set of Foose Legends with these specs.
18x7 4"backspacing and 224-45-18 front
18x9  5"backspacing  and  255-45-18 rear
This is what the tire place recommends, but I want to be sure.
It's a 70 Challenger Convert with stock rear springs that are not holding the rear up any extra. I have the front end cranked up and the rear with air shocks to compensate for the front. I'd like to put stock shocks back on the rear and drop the front with a slight rake (say 3/4 to 1").
Any thoughts or suggestions? Will the tire package I'm looking at accomplish the goal?

 :faint:

I don't even know where to start.  :eek7:

You don't need new wheels. You need a new tire shop, and a new alignment. In that order. That alignment is a disaster, and the camber bolts on the UCA's on these cars are easy to use. There's no reason they couldn't have done better than that unless your front suspension needs a rebuild. Lowering the car some would improve those numbers, but that's not the only problem. If the picture of your car is at it's current ride height, it's not sitting so high that they couldn't significantly improve the alignment at it's current height. You do need to set the ride height before you get a new alignment though if you're going to change it.

Positive camber and negative caster is for bias ply's. You have radials. So, the stock alignment specs need to go in the trash can, and you can start over with -.25* to -.5* camber, +3* caster, and 1/16" to 1/8" toe in. Your tire life, handling, and steering stability will all increase dramatically. Seriously, it will feel like a different car.

Not only that, but if you do that, more than likely your current wheels and tires will fit in the front and will no longer rub. I say that because I have 17x9's with 5" of backspace and 275/40/17's all the way around on my car with no rubbing. My front tires stick out an extra 1/2" further than yours do. An extra 1/2". That by itself should be all the clearance you need. I do run more camber, at -.9*, but even with -.5* you should be more than clear. I also run large torsion bars, at 1.12", so I will get less body roll than you, but STILL, you should have enough room to run your current wheels with a proper alignment.

Now, if you really want to upgrade to 18" wheels (and I don't blame you because the tire selection is MUCH better), the recommendations they gave aren't horrible. Personally I wouldn't bother with 225's up front, but I know some guys like to run the skinny front tires. If you don't, you could just run 18x9's with 255/40/18's on all 4 corners and be able to rotate tires. Or even 245/40/18's on 18x8's up front with 4.5" backspace and the 255/45/18's out back if you want to stagger and go with that tall back tire. The car will handle so much better with the wider front tires.
Title: Re: E-Body Tire Combos
Post by: Lotsapins on August 24, 2015 - 08:29:20 pm
Pretty much what they had told me at the alignment shop was with the front end so high, they can't get any more caster. The adjustment cams are all the way to their limits. So that being said the spec sheet has the caster in the red. I have bought the 18" wheels and tires and expect them in a few days. I will be taking the alignment numbers you gave and will have it realigned to those specs. I will get the ride height set to what I like and then have them do it. Just a quick question.. When yo showed the caster and camber specs, is it the same for both sides? and it the toe the total toe or is it per side. My guess is total, but I want to be sure. Thanks for the help and I'll be looking forward to the  new feel.   :cooldancing:

Lotsaspins -- regarding your alignment... do you at least have the Moog offset UCA bushings installed?  Or else, any aftermarket UCA (FF, PST, QA1, SPC, or Hotchkis?   You'll never get an improved handling alignment with the 100% factory setup... at least, have the Moog offset UCA bushings installed (done in reverse sides)... that'll get you some negative camber with POSITIVE CASTER that you absolutely need.   Better yet, bight the billet $$ and get some aftermarket UCAs... they'll change your steering for the best by allowing POSITIVE CASTER with some NEGATIVE CAMBER.   The POSITIVE CASTER is mostly sought after for the improvement... the factory OE parts can't give those allowances.

Probably can't go that way. This car is for sale, but I drive it for personal enjoyment till it sells. With the new wheels, it should clear and be able to sit lower. That will also give me a shot at the different alignment specs shown above. I also have found that I only have these rub issues when the car has the wheels cut all the way and one of the front corners dips down hard. This was a 318 car and I think it has the 318 torsion bars still under it. With the weight of the 440 I am probably dipping down harder than it should. I will probably try to find some bigger torsion bars for a 440 and stiffen the front up. I don't know what size or part number to use, so if anyone has this info it would be of great help. I should be able to get some + caster with it lowered in the front and with bigger torsion bars and the tire change, I believe it will all come into place.
Title: Re: E-Body Tire Combos
Post by: Mopar Mitch on August 26, 2015 - 03:13:05 pm
Actually... when the front gets lowered, or the rear gets raised, you're taking positive caster... introducing more negative caster... not what you want to do.

Regarding TBs... the factory units, regardless sb or hd BB (even the six-pack and Hemi TBs), they are all relatively weak.  I suggest at least 1.10-1.12.. or 1.15... if you're not changing the rear leafs, as well.   don't be afraid of larger TBs.... I run 1.24 dia on my T/A (setup for competition pylon autocross/hi-speed AX/road course events... and they are just fine on the street/hwy.... of course, as with any driving, you'll always want to avoid bad rough roads, or take it easier over them.... regardless of whatever TBs you have.  the stiffer TBs will definitely reduce excessive front end dive.. especially more with a BB engine car.    Contact Firm Feel for your best choices... 1.12 is an easy choice.   Don't be afraid of the extra stiffness... you'll only wish the car had come that way from the factory.

New wheels and tires on now. Also changed to 780-781 torsion bars (440 & Hemi).  Front end is stiffer now also.Got it re-aligned. Here is the new specs.
LF Camber -0.5*
RF Camber -0.7*
LF Caster 2.6*
RF Caster 2.3*
LF Toe 0.17*
RF Toe 0.16*
Total Toe 0.33*

It does drive better and after the torsion bars were changed, my specs were a mile off. They didn't charge me again
although they could have since I had altered the height and changed the torsion bars.
I will drive it some more this weekend, but I think it's good.

Front suspension is the 1" torsion bars and factory disk brakes. Wheels clear everything. The rear of the tire would hit the frame if it was any taller. It just misses by 1/2 when turned fully.u

Here is a better picture that shows the difference in wheel sizes front and back....

Got it! I noticed that's a pretty short tire, but I still would have thought that amount of backspace would have been too much. Good to know!

Yes. Previous owner did a mini-tub, leaf spring relocation kit, and used an A-body 8.75 diff. LOT'S more room for the larger wheels/tires. Engine was custom built by Carlos Gomez @ Submission Engines ( http://submissionengines.com (http://submissionengines.com) ). Don't know all the internals, but I believe he installed a custom cam. This guy knows his Mopar engine s#*t! Attached is a photo of the clearance of the set-up for the rear.

I took a chance because that was all that was available in that wheel, other than doing a custom backspace. It looks good with the smaller front tire.

Anyone running a 9.5 rim with 5.25 backspace with a 275 tire?  (http://images.tapatalk-cdn.com/15/09/24/8cf862264ea27ae798dc6dbe06c854c6.jpg)(http://images.tapatalk-cdn.com/15/09/24/992c1908669315e4da49a4bcd551542c.jpg)(http://images.tapatalk-cdn.com/15/09/24/a0f601c7203f01ae628c3ea7e83cbcfc.jpg)
That's the rear (275 50 17 which I know is way too tall). Looks like I'm going to be stuck with the rims so I guess I'll order the fronts...I'm thinking a 275 40 17 will fit but will be close.  I will be rolling the fenders and removing the brace....

Not quite, but I'm running a 17x9 with 5" of backspace and 275/40/17's in the front. The 17x9.5 with 5.25" of backspace has the same exact offset (0mm) as my combo, so the tire should be in exactly the same location on your car as mine. On the driver's side all I did was remove the brace, on the passenger side I did a little massage work on the fender lip, it's not even fully rolled. And my car sits pretty low.

The only possible concern isn't tire clearance, it's the rim clearing the outer tie rod end. The additional width of the rim, and therefore backspace, will make it a tight fit on the outer tie rod end. But that has a lot to do with the design of the inner edge of the rim too, so it will be hard to tell without mocking it up. You're into a combo that may or may not work depending on which rim you actually use. Some will, some might not. The only good news is that even if it doesn't clear, you're probably within a 1/8" spacer of making it work. And if you're planning on rolling the fenders, you should have the room.

Not in the cuda anymore but my 72 runner is very similar in a lot of ways.
Replaced the soft 8 blacks steel rims with the torque thrusts, but in all my research I found that American Racing now produces the TTs with a new type finish called PVD, which is similar to black chrome. I thought it looked cool so I bought em, through newstalgia. I think the darker color has an effect which hides the spokes a little. Makes them look smaller because the curved sides of the spokes blend into the dark background behind the rim. A big feature for me: the polished aluminum TTs require a lot of polishing to keep them looking nice. The PVD finish is a durable coating that doesnt need polishing.
Heres a link and a picture of the real thing. I think they work well on dark colored cars.

No Garlits. Would love to go but cant. I did drive it 75 miles each way to a show this past weekend and got a "best of show" They handed out about 20 of em, and there were probably only 60-70 cars there, so no big deal, but not bad for first time out. The car drove very nicely, but a slight vibration in the front end at about 70. Will have to figure that one out.
Anyways, I think the PVD finish looks cool, and urge anyone to check it out.

Great thing about these 71-72 runners. I never see them down here. In 6 years going to the Florida Nats I have never seen even ONE. Lots 0f 68-70s, and lots of 70-74 Cudas and Challengers, but no 71-72 Runners or any B bodies for that matter. Very rare.

What are the specs on the rims and tires?

If you really want to make Brad jealous, just show him how much clearance there is for extra tire. When I measured my '71 Satellite Sebring Plus with the 275/40/17's I have on my Challenger I figured out that you probably could fit 315's on all 4 corners of a 71+ Satellite/SSP/RR/GTX with the stock suspension and spring locations. With the 275's on 17x9's I had 2" of clearance to the front fender lip and still wasn't on the frame at full lock. Even leaving a 1/2" for clearance that would mean a 315 would work in the front with no mods. Pretty much the same for the rear, and you could still do a 1.25" offset kit from Dr. Diff...

These are just skinnies, but look at the ROOM!!!

Thanks for all the nice comments about the car.
And yes, there is definitely more room for rubber. Truth be told, I cheated. I have the following setup:
Front 17x8 w 4.5"bs and 245-45 bfg2
Rear  18x9 w 5.0"bs and 275-40 bfg2
But....I added hubcentric spacer/adaptors front and rear to fill the fenders out a little more.
added 1.25" front and 1.00" rear. Essentially it made the rims 9.25" front and 10" rear, without having to spend an extra $600 for custom order rims. The adaptors were not easy to find, but they are an EXACT fit (critical with adaptors) and they were less than $100 total.
And I still have some room to play with on the inside. I like the way it stands now, but yes you could fit 315s in the rear for sure. 18x9s in the rear and I have more than 2 inches room inside from the leafspring!

@3D.  Don't know if you're intending to reference a different quote, because the 'quote' you're replying to is not mine.  Regardless, the prior owner did other mods as part of the mini-tub and leaf spring relocation (i.e. frame stiffening), but there is no 'cage'.

Can't say either way regarding the Caltracs, as the car hasn't seen much road time since they were installed.  But, the little time it has seen, I'd give them 2 thumbs up.  Yes, I didn't realize that the prior owner had done what they did to the rear frame rail.  But like I said, they did other frame stiffening mods; mostly welded in custom sub-frame connectors, and possibly other things, etc.

Mopar Mitch, you are definitely right on your concern.  Air shocks aren't the way to do it, but that's what it's got.  It doesn't rub, but then again, it's the air shocks holding things up.  Eventually, I'd like to get the springs moved in, proper SS springs etc. down the road.  Also a 496 stroker to go with...all in due time. 

I didn't have to jack it up anymore than I did with the 275/60's on the 8" Rallye's.  The tires are just more massive giving that look of it being way up.  It does ride pretty good and doesn't track all over the road like the old Polygas GT tires did.  Those things looked cool, but were horrible to drive on.  Now it rides pretty soft even with the air shocks in back, doesn't bounce or jar like it did before. 

Some of that thing I hated about the Cragar SST and Polygas combo is that it was extremely heavy, putting a lot of unsprung weight on each corner.  This combo is a good 10lbs lighter per wheel which also helps the steering etc.

Mopar Mitch, thanks but I honestly hate the bouncy-ness of it.  I am thinking of changing to radial tires at this point and would like to go with a more square fat look and better ride handling, cause driving is important. 

I was thinking 265/50r15 front and same or 295/50r15 rears.  The only company that has those right now is Hankook with their H101 Ventus... now before I get flamed, I had a set of Hankook RS3 semi's on my old RX8.  They handled flawlessly and had tremendous grip.  I know there are many threads that beat to death about RWL tires and such, but I believe the design of the Ventus H101 is FAR superior to the BFG slippery T/A's.  Just my opinion, never had the H101's but looking at the tread design they have a better tread-pattern than the BFG's. 

Their are many other RWL options IF I choose to go with a smaller front tire.  I have a 235/60r15 on my Rallye's and not particularly fond of the skinny size.

JAS -- I've never run Hankooks but I'm satisfied with the newer BFG T/As on my car... just for street and mostly highway cruising.  255-60-15 fronts, 275-60-15 rears... mounted on vintage-style "Performance" brand 15x8 minilite rims.  "Street" truly doesn't count.

For better handling performance (hwy/road course lapping.. HSAX/HPDE), I use BFG G-Force Comp T/As.. 255-50-16 f/r on 16x8 minilite rims.

For yet ultimate handling performance, for competition pylon AX (SCCA) or HSAX, I use Hoosier A6 275-45-16 f/r on lightweight Centerline forged aluminum 16x10 rims.

Mopar Mitch, how did you fit a 255/60r15 on 15x8??? and what is your offset.  It doesn't rub at all?

I've run 255/60R-15s on factory 7" wheels on the back of several cars.  They look just the slightest-bit squeezed, but they worked very well.  Suggested rim width range is 7"-9" on that size, actually.  For my Challenger, I have 255/50R-17 Nitto NT555s on 17"x9" Minilite replicas all the way around.  The shorter aspect ratio demands a wider rim, but they still could've been squeezed onto an 8" without problem.  Though my car is still without an engine, I've driven these tires hard on other cars and been very impressed with the price:performance ratio.

Post by: Mopar Mitch on November 11, 2015 - 02:06:21 pm
JAS -- A 255-60 is no problem on an 8" rim, even for a 7" rim.   My rears are 275-60 .. previously on factory 7" rally rims.. now on 8" rims... no problem.  The taller sidewall does allow forgiveness without severe pinching, like on shorter 50-456-40-35 sidewalls would do.

My fender lips are flushed (f/r), car is lowered f/r, ... no rubbing at all.. tight stiff suspension helps prevent diving.

The 8" rims have a slight extra offset of 3/8" (pushing the rim out towards the fenders a bit)... still.. no problems.   I really like the taller sidewalls (60) with my stiff suspension setup -- it allows some extra cushioning (for "street)... and an overall comfortable ride.

Like I said, for better performance driving (HSAX/HPDE...road course lapping sessions), that's when I put on the better rims/tire setups... it makes a good difference overall.

JAS -- I previously had 245-60-15 on the front rims (rally 7" wide, as well as the minilite 8" wide rims)... 245-60-15 are too small, but ok.  The 275-60-15 rears do add a rake, and for handling, you don't want a lifted rear rake.... the added height of the 255-60-15s in front pretty much leveled the car for cruising (with minor stuff in the trunk... camping tent, sleeping bag, etc).

I wondering if I could get some opinions. I've read through all the posts but I'm still a little confused. I'm a novice at this. I am building a Pro Touring 1970 Barracuda and I'm at the stage where I want to order my suspension, wheels, and tires. I want to run a RMS Alterkation in the front and RMS Street Lynx in the rear with a 14in Wilwood set up. I want the car to sit as low as possible where I can still drive it everyday. If I run 18s on the front and back what size should I run to get the biggest widest tires with no mini tub. I'm confused on backspacing and the best tire combo to purchase. I don't want to make the wrong decision. I was also debating 20s in the back but for a street driver I think 18s may be better. Any recommendations would be helpful. Thanks

I have a 73 Barracuda with 69 B-Body width Dana 60, 1.5 inch spring relocation kit and caltracs.

I'm going with 10" rims with a 5.5 backspace. 

My question is can I fit 315/60/15 drag radials in the stock wheel wells?  I wont have any heart burn if I have to trim/roll the inner fender lips.

I know stroker did with a Challenger and I think his Dana 60 was about a 3/8 - 1/2" shorter than mine.

Have any of you guys run this or a similar combo or know someone who has??? 

Thanks for your time.

The 17x9's I have on my Challenger have a 5" backspace, and are almost perfectly centered with my '70 B body rear axle and a 1" relocation kit. I run 275's on mine, but I have room for another 2" of tire on my car. 325's would definitely fit, 335's would probably fit if I rolled/trimmed the quarter lip.

If anything I'd be looking for a little more backspace if you've got the 1.5" offset kit, maybe as much as 6" if you can get it with the 10" rim. The inner wheel tub will probably come into play before the springs do though.

My Challenger has an A-body 8.75 rear end which is 52-5/8" flange to flange.  E-body 8.75 is 56-31/64" flange to flange.  B-body 8.75 rear ends vary in width depending on year, but the shortest is '62-'63 @ 53-1/4" ( http://www.moparts.org/Tech/Archive/axle/16.html (http://www.moparts.org/Tech/Archive/axle/16.html) ). The previous owner did all the work/mods about 14 years ago.  They used a Mopar Performance leaf spring relocation kit, and did a mini-tub.  I added the Caltracs.  I have 10" w/5.5" BS wheels and 315/60-15 BFG Drag Radials.  It all fits very nicely.  However, the previous owner did modify the rear frame rails to better accommodate the tire/wheel combo. Don't know if your intended set-up will clear the fender lips.

Thanks for the response.  I have read it can be done with what I got.  If I have to trim I will.  Did you need to mini tub or did you choose it?  Looks like you might fight 325's under there?  How do those BFG drag radials hook at the track?

I'd have to get wider wheels with a different BS to go with wider tires (i.e. 11' wide w/6.5" BS, or 12" wide w/7.5" BS).  Right now there's about 1/2" clearance between the tire and the fender/wheel lip.  The previous owner did the mini-tub.  I assume they felt it was best or necessary.  Haven't had the car at the track yet.  I've been doing a ton of work on it gradually since I bought it in 06/2006.

Fronts should work with either tire. The 275's will probably need the fenders rolled. Keep an eye on your outer ball joint clearance, you might need a small spacer. My 17x9's are "0" offset and it's pretty close on the outer tie rod, but that depends on the style of the rim too.

In the back I'd stick with the 285/35/18 if you've got the stock rear end and spring locations. Should be ok with a roll on the quarters. A 295/45/18 is nearly a 29" tall tire, and anything with a lower profile than that won't fit on a 9.5" wide rim. With a +10 offset you might need a small spacer to adjust for spring clearance, but that's easier than the alternative.

6packcuda, thank you for the reply.  When you say had to shave the lip completely off, do you mean the inner lip inside the wheel well above the tire or the folded lip attached to the quarter panel?  Thanks again!

Yes, I used the Dr. Diff 1" spring re-location kit. Everything I read and Dr Diff himself told me everything would clear the springs fine with my set up but, for whatever reason, after I got it all bolted together, the tires did not even come close to clearing the springs. I had to modify the shackles to move the springs in another 1.5" in the rear. Because of that, I also had to re-locate the spring perches. I've racked my brain trying to figure out what is different but no luck. After my modifications I have about 1/2" clearance to the springs.

 Despite what the mopar book says, 62-65, 66-67, and 68-70 b body rears are all different widths. This will directly impact where the wheel assembly ends up which will then impact rim  offset selection.

Very true, but the '70 he says he's using is the widest of all of them. Unless it's not actually a '70 B body rear end. A '68-'70 8 3/4 B rear should be 60 1/8" drum to drum (54 15/16" flange to flange), a 65-67 8 3/4 B rear should be 59 1/2" drum to drum (54 1/4" flange to flange).

'62-63 and '64 were also different widths, but I usually don't pay much attention to those because they have tapered axles, the kind that has the drums retained by a nut on a taper with a keyway.

So it very well could be that B body rear wasn't actually '70, but a 65-67, which would need less backspace.

It's a '70. I had to order the '70 only brake lines for it. The vent/T fitting is in a different location on a '70.

you will have a good inch of fender lip clearance, might be close on the inner fender wall, with no leaf springs that should be you limiting factor, I have 15x10 5.5bs with 295's on 1" relocated springs, tight on the fender lip, plenty on the inner clearance, my springs are my limiter, Ihave about 1/4" to the leaf.

Hello, I've read threw quite a bit of this thread, but I just wanted to see if I could confirm this.

Although it might be a bit, I'll be looking at buying some 15x10 (back) wheels and fit as much rubber w/o cutting anything up on my 71 challenger. I have a b body rear end out of a 69 1/2 a12 Coronet dana with 4.10 gears, that I plan on putting in my challenger to help with tire clearance. I purchased the Dr Diff 1" offset shackles. He recommended I run a 28x12x15 (305x54x15) MT Street Radial on a 15x10 wheel with 5.5 inches of backspacing he said it will work w/o spacers if I use his rear disc brake setup. So the question I have is has anyone else done this setup? Not sure what to run in the front yet, right now I am focusing on the rear and making sure things fit w/o any tubing/cutting. I'm also looking at running the caltracs leafspring/traction bar setup as well.

Dr Diff knows his stuff, so you  would be safe with his combo. I have a very similar set up and have clearance both inboard and outboard. Mine is a 66-67 B body housing, 1" offset springs, 15x10 with 5" backspace ( the 68-70 would use the 5.5") and a 26x12x15 MT tire. No other mods at all.

Up front  I have 15x8, 4.5" backspace, 26x10x15 MT tires.

Just for grins, I have tried mounting the 15x10 combo up front. They are gonna require fender surgery to work up there. This is where a 17"+ sized rim would help. The max backspace you can run on  a 15" rim is 4.75 before it contacts the ball joint. Larger diameter rims would clear this and allow more backspace so there is less tire sticking out.

Thanks for the reply back. So you are running a 26x12x15 at the rear (Not 28"s tall?) I'll shoot for running what he told me (28x12x15) just wanted to see pics and confirm fitment if possible. Maybe it's me, but it seemed like there are more wheel choices for 5"bs vs 5.5"bs. I need to look more though. As for the front, I'm not overly concerned with putting the biggest wheel tire/combo up front. I just want to make sure I can turn the wheel fully w/o rubbing.

Yes, I've limited height to 26" all around. However, a 28" tall tire is only 1" larger top and bottom, so still not a big interference issue. I may run 28" when I wear these out, unless something new comes to market.

Backspace, options really vary among different manufacturers. With cast aluminum wheels you really are stuck with what they have. No chance of them changing molds for a special request. Forged, 3 piece or steel wheels tend to have a lot more variability and options for custom spacing.

I would stick with the Hoosier Quick Time 26x12x15, it looks good on a Challenger.  I had 28x12.5x15 Mickey's on my car and didn't like the look with 26" in the front.  Too much rake.  Check out Hoosier for that 26" tall 12" wide tire, Mickey unfortunately discontinued there 12" wide 26" Sportsman Pro, but they have other radials close to that.

Please advise me - why go for such a fat tire? Maybe my question sounds stupid, but give me a break - I'm from Central Europe, we don't get muscle cars over here.  ;D

So, why not go for a 17/18" wheels with thinner tires instead of 15" with fat ones? Is it to be drag raced, just for looks or what?

BTW, I checked, even if I wanted to get tires like those, I'd have to order them from somewhere because they are not available in my country.  :thinkerg:
Title: Re: E-Body Tire Combos
Post by: JAS on December 23, 2015 - 01:31:21 pm
I guess, I assumed you were running or thinking of running a 15" wheel.  I can give you advice on 14" and 15", the other's I can't because I've never tried to run them.  People who run larger aftermarket brakes usually run the larger diameter wheel, thus the advantage there.

It comes down to what you like.  I prefer more stock/Day 2/70's look, so a 16" will never be on my car.

Yeah, I planned to go for 17" in front, 18" in the back, but then I saw this thread and started thinking maybe 15" is the way to go... I didn't know if there is any other reason except looks. The grip is the same or...?

The questions you are asking there are many answers to.  Ride quality, handling, etc. all come into play with different arrangement.  Something to keep in mind in general, the shorter the sidewall, the harder the ride ~ not necessarily better cornering, that has more to do with tire choice and compounds... see what I mean about different answers?

Limited in the US, over here N/A!  >:(

I will start to look for wheels, but finding something by European manufacturers that will fit the looks and required sizing of a Challenger might be impossible. I might end up ordering from the US which will cost at least twice than I would pay if I could find some European wheels.

Sure thing. I used to drive only Alfa Romeos, this is my first muscle car. I still have to get used not to be able to hit the corners and live to tell about it.  ;)

So yes, cornering is VERY important for me. Roads here are narrow and twisty so I'll have to set up the suspension, brakes and tires for handling.
Title: Re: E-Body Tire Combos
Post by: JAS on December 23, 2015 - 01:47:49 pm
Not sure where in Europe, but 15" sizes are very easy to find in all kinds of tires and sizes here... it's 14's that are limited in my opinion
Title: Re: E-Body Tire Combos
Post by: HP2 on December 23, 2015 - 03:20:43 pm
Perspective I suppose. If you need street cruiser or drag racing tires, there is a decent  selection in the US of 15" tires. If you need speed rated, high ply construction, or high grip, d.o.t. approved UHP 15" rubber, there is virtually no choice, IMO.

Yes, typically for drag racing you want a lot of sidewall to cushion the impact on the tread face that is produced by the high rpm of the green light launch. In contrast, in a handling application you typically want a more rigid sidewall to reduce deflection and improve slip angles. The two disciplines are not very compatible.

Original equipment providers are continuing to put ever increasing diameter wheels on vehicles, so the selection of tires for sizes popular 5-10, or 15 years ago is shrinking, never mind finding true ultra performance tires for rim from 30-40 years go. This is why so many are migration to 17, 18 or even 20 inch rims. I surmise that eventually some of these custom width, large diameter tires will also disappear unless you are using a size that was offered widely on OEM manufacturer's vehicles.

There may be any number of wheels in central Europe that could be made to fit. The classic mopar bolt pattern is 5 lug on 114.3mm spread. There are numerous cars that utilize this pattern such as Acura, Bentley, Honda, Nissan, Mitsubishi and others. The biggest challenge with be finding a width and offset that is compatible with the suspension components in your Mopar. Similarly, if you go with 15" wheels, you can find some vintage tire offerings from Dunlop and Avon that have a fair amount of distributors in Europe. Will it be easy, no, but certainly not impossible.

Of course, all of that is contingent upon your countrie's restrictions and requirements for vintage vehicles. I know that some EU countries will only allow original or originally optioned equipment to be on cars that are licensed as vintage.

Any mods to make the rear fit?
Title: Re: E-Body Tire Combos
Post by: ed-pv on January 11, 2016 - 07:52:29 am
Surprisingly, there were NO mods necessary to make the rear fit!  There is actually room left over.  For the fronts, my front lips were rolled for another setup and would probably need to be rolled to make the 18's not rub in turns.  The front end does have QA-1 and Hotchkis parts, so I am not sure how the stock front end would work.

Regarding the ride quality, with the 18's I do feel the road a bit more, but nothing to be concerned with.

I currently have 255-60-15 T/As front, mounted on 15x8 minilte rims (and 275-60 15 rear on same 15x8 rims).   These same tires will also mount and work fine on factory 15x7 rims.  You can tuck the lips in for added peace of mind if you want (my car is already lowered).

Thanks MM!! Backing up, in a tight turn, does your tread scrape the front lower edge of the fender/ trim? Mine did, long ago, old tires, dont remember the size.....lol

Title: Re: E-Body Tire Combos
Post by: Mopar Mitch on January 29, 2016 - 12:33:25 pm
ERAT340 -- no rubbing on the front edges of the fenders, nor upper lips (rolled lips and slightly pulled... but again, I've got a stiff suspension, so, hardly any dipping at all.... even considering that my car is lowered f/r.

My fenders are slightly modified to accommodate 16x10 rims (5" back spacing... pushing the tires out towards the fenders ~1/2" from a stock dimension setup) with 275-45-16 DOT Hoosiers A6 race autocross tires.... no rubbing and just enough clearance.

If you'd use correct offset/backspacing, then the 255-60-15 will work without any problems, nor any need to modify the fender (again, tucking the lips for additional insurance would be the most needed to do).   

One thing, perhaps with most wider tires, or taller tires, too, is the front rear inside will rub slightly against the frame rail when turned to a lock... no big deal.. just a bit of rub.

We really need more information about your car and wheels. What are the dimensions of the rear end (how much was it narrowed)? Are the springs relocated to the frame rails? Has the car been mini-tubbed? What is the backspacing measurement on the wheels?

Without that info there's really no way to figure out what will actually fit on your car.

 I agree, a 15x10, 4.5 backspace on a stock E body housing, set up with 295/60s won't fit within the wheel wells.

I have a similar set up to crash340s but with slightly different results; '67 B body rear, 1" offset rear suspension. I'm running 15x10 with 5" backspace and a 26x12 (305/45 in metric terms) and I have about three quarters to an inch on each side of the tire. Of course, there are different width B body housings, so this can impact things as well. Mine is also in a Challenger. Rumor is Cudas are more stingy with clearance.

Yes I couldn't run 5" bs, unless I rolled the fender lips but I'd also have to raise the height of the car. When I go to 18" rims, I'll go to 11" wide and prob 305's, maybe 315's as there is no sidewall bulge as such

I'm looking at Yearone Mopar Ralley wheels : 17" X 8" ; 4.25back space with a 225/55-17" BF comp tire. for  the FRONT of my 1974 cuda with original disc brake style. 9.20" sidewall width and 8.70" tread. The diameter is 26.80". speed W rated.
      Will this fit like a 245/60-15" since it's similar? @ 9.47" Sw. with 8" tread and 26.55" tall. T rated.

26.8" is a really tall tire in the front. It's not much taller than your 245/60/15's, but it might not take much to run out of room at that point. I try to keep my front tires closer to 26". I'd be more inclined to look for a 245/50/17, which would be close to the same 26.6" tall tire you've got now, or even a 235/50/17, which would be around 26.3.

You can go wider , a 255/45/17 would work too, that's 26" tall on the nose. I run 275/40/17's on the front of my Challenger with 17x9's and a 5" backspace. They're a little shorter at 25.7", and require a 9" wide rim, but a 255/45/17 would still have clearance all the way around on a 17x8 with 4.25" of backspace.

The 225/50-17" BFG.Force Sport on the 8" Rally wheel will shorten up the tire, but still using the "Max. width wheel for any tire".
     Section width is still at 9.2", on a 26" tall dia. tread is 9", and this should be what I'm looking for @ $116.00 each.  Some sizes are not available in that price range. I'm getting them from Summit, mounted and balancing service for free. YearOne Ralley cast Wheels won't be in until Aug. 12.

Cuda's have a little more room in the rear than the Challenger but not much.  However every car is a little different too since assembling cars 45 years ago was not an exact science.  I have bought several wheels and tires from www.performanceplustire.com (http://www.performanceplustire.com).  They have great prices and service delivered to your door.

That set of wheels is what I want. And the original style fits the car.
     Does the inside of the wheel's center bore, fit the disc or rear axle,  drum hub like a stock one?
     Also, will solid valve stems clear the rims inside edge?

14" rallye wheels came off and these went on. No fitment issues at all.
Don't see why you couldn't run metal valve stems if you wanted too.

The valve stems have to be pulled through due to the recess. They fit the hub like a stock wheel perfect.
     One wheel was damaged in shipping so I'm waiting now. I bought the 225/50 R17" Goodrich Comp W rated for the front. It clears the front edge of the well by 3/4". I suppose a 235/50 would have fit too. I wanted the tire to be trim and not have any side waddle that comes from a wider or taller tread. Or any of the other suggested sizes. I want to make city turns, quickly and easy to maneuver.
      The tire's actual size is less than posted. The 9" tread width, is edge to wrap around edge. It only has 7.80" on the ground with full car weight. The height is 25.35", not the 25.80" advertised. So that's why a larger, 4 same size tire approach would be better for those with power steering. My wheel's weight @ mounted is 53 lbs. Wheel's 21 lbs. A bigger tire adds another 5 lbs each.
      My front fender top is even to the top of the tire and they sit far in, like stock looking. I have 10x29" slicks on 8" Welds out back for now. Dr D kit 68 housing Moser axles, MW spool 5.13. It fits with a 7/16 spacer and over 1" to the leaf and well top, it has 1 3/4" room to the front opening for growth and side waddle.

Mitch, is it for sure that the YearOne 17x9 Rallye-rims with 275/40-17 rubbers clear out on all 4 corners with no issues / no mod`s needed on a 70 Chally R/T with stock front/rear-suspension?

Se 72bluNblu comment... July 16, 2016:

"...I run 275/40/17's on the front of my Challenger with 17x9's and a 5" backspace. They're a little shorter at 25.7", and require a 9" wide rim..."

Since the Year One rims are CORRECTLY offset, at both 8" and 9" widths, there's no reason why a 275-40-17 tire mounted on a 17x9 rim with the correct offset/backspaing shouldn't work.  The tire is relatively small in its diameter.

My car is lowered f/r using 16x10 rims with zero offset (5"backspacing), which pushes the tire/rim outwards ~1/2 inch from the preferred correct positioning.... using 275-45-16 Hoosier A6 DOT Autocross tires... flushed the lips, pulled out a little, appears stock... IF the rim's offset was correct at 5.5 ", then I'd probably NOT have had to make those mods (again, car s lowered for autocross competition).

I suggest you re-confirm with our comrad 72bluNblu here as he has a Challenger and ruins 17x9 275-40-17 both front and rear.... I'd run them easily on my car, even without any lowering or slight fender mods... I'd be 100% certain they'd fit A-OK.
Title: Re: E-Body Tire Combos
Post by: 72bluNblu on October 07, 2016 - 12:15:23 am
My ears were burning!  :biggrin:

Yes, 275/40/17's on 17x9's with a 5" backspace should clear on all 4 corners. My car sits pretty low, so, I have removed the brace that runs from the inside of the fender to the top of the wheel arch on the inside of the fender. That's a ride height thing though. At the stock ride height that probably won't be an issue. I run with my headers about 3.75" off the ground and the top of the wheel opening at a smidge under 25". That brace can be removed even on a finished, painted car without disturbing anything if done carefully and can't be seen from the outside. And it may not be necessary, just depends how low you are.

Usual caveat applies, the body tolerances on these cars are not exactly precise and every car is a little different. A 275/40/17 fills up almost all of the available space, so, it's not a guaranteed slam dunk, but it should work.

Also, I'm pretty sure that Year One actually advertised 275-40-17 tires on their 9" wide rims for BOTH front and rear onto an AAR Cuda... and I tend to favor the Challenger has slightly larger wheel well clearances (your measurements may differ).

I think I have heard that the Challenger has wider REAR wheel openings while the Cuda has wider FRONT wheel openings. I would like to know the true answer to this though.

It could be but I don't know for sure. I know cudazappa was running 275/40/17's on 17x9's with a 5" backspace all the way around on his 'cuda, as I based the sizing for my challenger on his. I don't think the front is that different. Based on some of the rear tire sizes I've seen, the challenger's may have a little more room in the back, but I don't have measurements to prove it.

What is your current wheel size and backspace and tire size? Compare how much bigger your desired wheel and tire size is compared to your current set up and you can decifer if they will fit.

8" with 4" backspace or 7" with 4" backspace? You already look like you have potential wheel opening interference if you compress the suspension.

275/50r15 = 11.1 sec width x 26.4 diameter.  295/55r15 = 11.9 sec width x 28" dia.  So it will be roughly 1/2" wider on each side and 1" taller all around.  8" with 4.5" backspace will put the  tire 1" closer to the leaf, 1/2" for the rim, 1/2" for the tire. Hows the space to the rear section of the leaf spring 1" further back?

Don't forget that with the stock suspension layout, the springs are wider in the shackle area than they are in the hanger area. You will contact the springs behind the housing before you contact them in front of the housing. I don't see a 10" rim fitting without interference on either side. 5" backspace will put it into the leaf. 4.5" will put it into the wheel opening.

The car is in storage right now so I will have to get some measurements . I would like to get the 295 /55/15 Tire on with a 4  1/2 BS . Right now I have a 285/40/18 Tire on with no suspension altered . So the car now sits to high and needs to be lowered if I keep those tires and rims on it . I have decided to go old school with steelies and a cap now and that's why I was just wondering if anyone out there has a 295/55/15 Tire with a 4.5" BS on a stock suspension. I don't want rub issues so I always go what might fit and rub a bit to the next size lower so it never rubs !

Wheels came yesterday.

They are for the 69 Fastback G3 Hemi Project car.
It will be 2015 Viper Gunmetal Pearl and the Year One Rallye Wheels Matte Black with Dark Argent 71 Centers.
Plasti-Dipped just to see if we like it.
We Like It!  :2thumbs: :aarg: 
They will be going out for Powder Coat. Keeping the centers just the way they are. The wheels will be All Black, 100% Only masking the mounting surface,

I think you're going to need more backspacing.

In the front it will depend on the brake kit. If the brake kit you use has the same track width as 73+ mopar disks, it will work. But a lot of aftermarket brake kits add track width, and an 18x9 with 5" of backspace will put a set of 275/35/18's at about the minimum clearance you'll need to the fenders. I run 275/40/17's on my Challenger with 17x9's and 5" of backspace, but I've got no extra room to the fenders. I use the later 11.75" mopar disks on that car. So, whatever your brake kit adds to the track width you'll have to add to the backspace in the front to make it work.

In the rear you need more backspacing. 295's will fit, 18x10's will fit, but with an E-body rear axle you'll need more backspace. Again, on my Challenger I run 275/40/17's and 17x9's with 5" of backspace. I also have a 1" spring offset, but I used a B body rear axle. That combination is pretty close to centered in the wheel well with over an inch of clearance to the quarter and the frame. An E-body 8 3/4 is 1.5" wider than my 68-70 B-body 8 3/4, so right there you'd need an extra 3/4" of backspace. Most rear disk kits add the thickness of the rotors to the track width, so, typically a 1/4" or so. So in the back your 18x10's should probably have about 6.5" to 6.75" of backspace to make 295's work.

I just came across this option on the Jegs website for viewing different size tire and rim combinations.   For E Bodies, it only has a Challenger option and only for 1971.   There's also an option for some different body colors.    Even though it's a bit limited, I thought it was a good tool for scanning through a bunch of options quickly.

I've seen a number of references in this thread to using the Dr Diff spring relocation brackets to make more room for wider wheels in the rear.   It's not mentioned in the threads, but I'm assuming the spring perches have to be moved inboard to use these relocation brackets, correct?   I have a stock E Body 8 3/4" axle on my Challenger.   I know there's also an option to go with one of the narrower B Body axles to allow for wider tires and rims but at the moment it's not something I want to take on.

Yes, The kit comes with both the offset hangers and shackles. The B-body rear end housing is then a bolt in and allows the more readily available 5" backspace on a 10" wide rim.

If you retain the E body rear, then yes, you need to move the spring perchs over as well. You can still fit as wide a tire as using the B body rear, but it will require more offset.

Thanks for the quick replies guys. This is one of those "next time, I'd do it different" things since I already have the stock axle cleaned and painted, new seals installed, cleaned up the studs for the backing plate and have new bearings pressed onto the axles.  I found some B body axles a couple of hours from here on Craigslist, so now I'm debating again.  I'm trying hard to get the wheel and tire purchase "right" the first time so I only do it once.  Based on what I've read on this thread, there always seems to be an eye pointed towards an upgrade in the future.  I'm pretty sure I've spent more time thinking about wheel and tire combos than anything else we on my car. 
Title: Re: E-Body Tire Combos
Post by: dakota on March 19, 2017 - 08:25:36 am
I think I'm pretty well settled (FINALLY!) on the tire and rim size for my 70 Challenger.   The car has a stock E body rear axle.   When purchased, the car had 245/60/14's on stock Rallye 14x7 rims all around, a 14" spare, and power drums on all 4 corners. The front control arms and rear leaf spring are staying stock.  The "pretty well" qualifier is added because they're still a couple of questions below about how these choices might limit future upgrades.   I'm keeping the rear drum brakes (11X3) for now and have changed the front to disc with a basic kit from Right Stuff.  While I like having the look of the 17" front / 18" rear, the practical side of me has the choice heading towards using the 17X9 wheels with 5" backspace and 275/40/17  tires on all 4 corners that 72bluonblu is using.   I like the ability to rotate the tires around all 4 locations to keep tire wear relatively even, and in a pinch can put the existing spare to work (flat front tire means moving a rear tire to the flat location, then the 14" spare goes on the rear).  If I've done the math right, the 275s will be just a little taller than the 245s on the car now (25.7" versus 25.4"). 

So here are the questions assuming that the 275/40/17s on 17x9s with 5" bs are on the car, keeping in mind that I'd like to avoid having to roll or trim any fenders or remove any internal bracing: 

1.  Will using 275/40/17s with 17x9s on the front limit my option to use 2" drop spindles at some point in the future? 

2.  Along the same lines, would there be any fitment issue with dropping the rear axle an inch with blocks if that's something that interests me later? 

3.  Will there be enough space on the back to upgrade the drums to disc brakes if that's in the future?

BTW, thanks to all the folks that have been posting their wheel/tire info on this thread.   It's a lot to read through, but all of the info minimizes the risk of an "oh shXt" moment later for those of us going through this for the first time.

The decision about buying American Racing Torq Thrust II or Cragar S/S wheels will come later.

1. No, I ran 2" drop spindles briefly with my 17x9's. BUT, you don't need drop spindles. If you increase the diameter of the torsion bars enough you can lower the car more than is practical to drive on the street. All you have to do is match the amount of travel the torsion bars use to the amount of travel available at a given ride height. The larger the torsion bar, the less travel that is needed. With the 1.12" torsion bars on my Challenger I was able to lower the car with the torsion bar adjusters to the point that it was just as low as it was with the 2" drop spindles. I actually raised the car up a 1/4" from where I had it because I got tired of dragging things on speed bumps and driveways. Drop spindles cost more money than torsion bars, for the price of most of them now you can get larger torsion bars and good shocks to go with them. Not only will the car "look cool" with the lower stance, it will actually handle better too. The suspension geometry is better without the drop spindles as well.

-also, you mentioned you're running Right Stuff brakes up front. The 17x9 with 5" of backspace is figured for the 73+ Mopar disks. Different brake kits can change the track width, and I don't know what the Right Stuff brakes do as far as changing the track. The Right Stuff brakes appear to just be aftermarket supplied Mopar disks, but I could be wrong on that.

2. Shouldn't be, assuming that your backspacing is correct and the 275's are centered in the wheel wells. The 17x9" with 5" of backspacing should be close with the stock E-body rear and stock spring locations, but remember that I actually run a 68-70 B-body rear and a 1" spring offset. I have a TON of extra room. I know that 275's will fit on cars with the stock rear and spring locations, but, what I'm saying is measure your car to make sure that backspace will work for you. It should be pretty close, but all these cars are a little different and if you're making it that tight the body tolerances matter. If you do the 1" spring offset you'll want more backspace than 5" with the E-body rear to take advantage of the extra space inboard.

3. Depends on how your backspacing works out. Disks usually add a 1/4" to 5/16" per side, so, you'll need that much "extra" room to the quarter. If your goal is not to buy new rims when you upgrade you'll want to set your backspacing to put your wheels as close the springs as possible with the drum set up, otherwise you might not have the extra room.

Thanks much for the detailed response, particularly on the torsion bars.  The drop spindles and the adjustable control arms that might have to go with them are a $1000 decision.  The torsion bars upgrade looks like a much better alternative.

Dakota -- don't be afraid of bigger Torsion Bars... the Firm Feel 1.12 are just fine, but you could go with their readily available 1.18 diamters.... and you'll be amazingly satisfied. I run the maximum 1.24" diameters that fit inside the hex opening (rated at 425#/inch)... yes for competition purposes, but A-OK on the street/highways.... of course, to always avoid extreme rough roads or just drive more slowly over them.

 Watch out for too fat a tire on the front, or all 4's for rotation.
     Stock sway bar Cudas get sluggish wheel response from a tire that would fit on a 1" wider rim. I know on a 112" vs 108", a longer chassis can also use bigger.
      Example:    9" wide 17" mag on the cuda front will weigh more and steer sloppier on country S-turns than the 8" x 17" Rally.
      The back tires will cause over steer on freeway on ramps, if more than 1" taller. If the front tires are not tightly stretched, the max rated speed will be slower too.
       It's up to the individual to decide what they expect. I miss the extra sidewall bulge for flat protection, but the new stuff handles better. And I noticed all the new H.P.U.S. and import cars have the wheel sticking out more than tire. I see a lot of new gouged mags lately.

If your phone camera program is like mine on the Samsung galaxy, the photo rotation taken can vary depending on how the phone is oriented, that can be overridden by twisting the phone to align the camera symbol on the screen.

Very nice car and tire combination!  I'm looking at the exact same sizes, but with American Racing Torque Thrust style wheels (AR105M).  If I go with 17x9 in the rear, the only backspacing available is 5.94 inches.  Do you remember if your wheels were exactly 5.0 backspacing on the rear?  If so, how much clearance do you have in between the rear spring and tire?  I'm afraid if I lose almost an inch I might have issues with rubbing. 

Thanks!

yep, 5" backspace for the 17x9" YO Rallye Wheels
Just went out and measured both sides.
1-1/16" to 1-1/8" from leaf spring edge  to the back side of the both rear tires at the closest point.

After two years of photo shopping countless 'Cuda's rims, tires and stances. I have my favorite wheels on my Redfish and couldn't be happier. I had to add a 2" lowering block to get the stance exactly where it needed to be. The rims are 18" x 8" with 4.5" b.s. front and 20' x 9"with 5.75" b.s. on the rear. There is plenty of clearance everywhere with no fender trimming.

JimK, I too wanted 9.5's in the rear but Billet Specialties does not offer these rims in the half sizes.
I had 17's on the car before I tore the Pro-Touring teardown and thought I wanted 17's and 18's. My best friend talked me into the 18's and 20's, and while I'm extremely glad I went with them, this was the most tormenting decision I have made getting here.

You have any pictures to post of your car with new wheels and tires?

15x7.  With 3.75" backspacing.   Will these fit on a 70 barracuda? 8 3/4 rear end.  What tires should I run if so?

Thanks Mitch, I am very pleased with the end result. I was set on 17's & 18's but got talked into the 18's & 20's by my best friend and boy am I glad I listened to him.
The fit  is spot on also with no rubbing or clearance issues anywhere.
Cheers!

Well, after quite a bit of digging and research the wife and I have decided on MB Old School wheels in gunmetal with a polished lip, and Nitto NT555 G2 tires.  The fronts will be 17x8 with zero offset (4.5 inch backspacing) with 245/45zr17 tires.  The rears will be 17x9.5 +6mm offset (5.49 inch backspacing) with 275/40zr17 tires.  If my measurements are correct, the rears should take up pretty much all of the available space width wise when using stock suspension.  I was having trouble with the backspacing options available on the 17x9 or 17x9.5 wheels in most brands.  The MB Old Schools were the only ones that we could find that we liked in the under $200.00 each price range that didn't have 6 inches + of backspacing.  The tires are identical in diameter, but the combination allowed me to go quite a bit wider on the rear.  I'll post photos once they arrive for additional reference.

Thanks to everyone that has previously posted.  The information helped me quite a bit!

After two years of photo shopping countless 'Cuda's rims, tires and stances. I have my favorite wheels on my Redfish and couldn't be happier. I had to add a 2" lowering block to get the stance exactly where it needed to be. The rims are 18" x 8" with 4.5" b.s. front and 20' x 9"with 5.75" b.s. on the rear. There is plenty of clearance everywhere with no fender trimming.
Cheers!

Mustardbucket,
Tires are 235/55r18 on the front and 255/55r20 in the rear.
Suspension mods are a complete Hotchkis TVS system with a 2" block in the rear. Large Wilwood brakes on both ends.
Cheers!

I had the same size tires on 17's & 18's and they fit great.
Neither those or the18's & 20 rub anywhere and no trimmimg. And the suspension was all original.

Hotchkis is a stock replacement system, so it does not necessarily move anything around at all that would impact wheel selection. However, without the 2" block that Mick has, yours would sit higher in the rear.

I ordered taller tires for the rear, but I'm thinking of 1.5" blocks until I can afford a 4 link. Priorities tell me my 416 needs to be finished

After years of combo's, I finally came up with what I thought was the perfect set-up with BFG's on 15" rallye's.
Car is lowered all the way around with the biggest torsion bars MP had for circle track racing, and hemi leaf springs in the rear - KYB shocks.
Fronts fit fine, I had the rears made to get a 1/4" clearance from the leaf springs and just clearing the fenders after rolling them.   
I would have to dig out my notes for specs - its been about 25 years.
Car handled well and looked perfect!
 
front: P275/50R15 (25.825" dia)
rear: P295/50R15 = (26.61" dia (24.9" OE) x 3.55 = 3.301 effective ratio) 

Now I need new fronts & they are discontinued!

For many decades, I've always considered 16" rims truck wheels. For muscle cars it is either 15" wheels or 17" wheels. Tire availability is the reasoning behind this thinking.

Tires are a very personal preference but I run 16x8's with 4.5" off set front and back and for tires I run Toyo R888 in 255/50R16 front and back.  There are also BFG's available in this size.

A nice day to get the Cuda out finally.
Firestone Wide Oval Indy 500 on Year One Rallye Wheels Front 245/45R17 17"x8" 4.5" BS, Rear 275/40R17 17"x9" 4.5" BS
Both front and rear tires are 25.7" tall. Still sitting on old suspension. Every corner is a different height right now... :screwy:
That should change when I get all the new suspension on. Torsion Bars, ESPO Leafs... :working:

Hey guys and Randy,

Getting ready to reshoe and rubber for my latest acquisition, a 1970 Challenger 340/4 Speed and while I absolutely love the stock 15" Rallye Wheels, I likely will upgrade to the 17" Year One Rallye Wheels similar to Randys 8" on the front and 9 on the rear.

One question for all, is how flat on the 17" rims will the 245s on the front and 275s on the rear fit?  Don't want all of that rubber to roll over the sides! 

I imagine should have plenty of clearance with the stock suspension which I intend to lower a little.

Any thoughts greatly appreciated....

Challengermaniac -- I suggest just going with the YearOne 17x9 both front and rear.. and using tire size 275-40-17 both front and rear.   Anything smaller (rims/tires) ... you'd just be cheating yourself of the available rim width and tread width.   YearOne made the correct backspacing/offset for these rims, in particular for the 17x9.. so to use 275-40-17 tires sizes both f/r with those rims.   Furthermore... with same size rime/tires f/r, you can rotate.

Thanks for the reply and info.  All I can say is Holly Gee that sounds HUGH! 

Does anyone have pictures of:    17x9.. with 275-40-17 tires sizes both f/r with those rims?

Post by: Mopar Mitch on October 12, 2017 - 01:48:23 pm
Challengermaniac -- 275-40-17 tires are not as big as you might think... their overall diameter (25.7"... on the small side amongst most other tire sizes), combined with the critically correct rim backspace/offset.. hats-off to YearOne for making them correct!)... makes this combo work easily for our e-bodies, even if the car body is lowered.   I believe YearOne's picture advertisement of the AAR has 17x9 f/r with 275-40-17 tires f/r.    We have some c-c members here with that combo already.

Are you sure 275 would fit in the front w/out rubbing? YO ad/photo shows 17x8 w/ 245 tyre in front and 17x9 w/275 tyre in the rear.

I have the same doubt because going for all 4 tyres of the same size would mean I can switch them around.
Title: Re: E-Body Tire Combos
Post by: Mopar Mitch on October 13, 2017 - 05:36:43 pm
I believe YearOne even promotes 17x9 with 275-40-17 front and rear to fit a-ok.... read their promo ads in detail (I know I've read it).    Further, you can draw some diagrams and see for yourself... because of the correct backspace/offset (speaking of the larger 17x9), that tire size fits a-ok.  Again, its really a relatively short diameter tire (275-40-17), and the extra width isn't much at all.   IF your suspension is weak/soft, you could slightly turn the lips inwards for peace of mind... and that would only be a concern if you'd be driving hard ... cornering hard.

Don't forget the 225/50 X 17" on a 8"x 17" wheel for the FRONT AAR rake.
    The BFG Comp2 @ 25.5 actual, X 9.0" wide tread.
 9.5" SW on a 8" rim, (9" full rim width). notice how the tread and Side dimension, on the widest rim for this tire are close. W speed 168mph It's perfect.  If tire is any larger it would require power steering.     

     255/45-17 Comp2's on 9" Yearones is the matching rear wheel/ tire setup. The 9" x 17 Yearone Wheels are 28 lbs.

For me, currently with a 5.13:1 spool, I have to go with the Nitto's since I have the 12 lb. 10" Billet wheels.   Nitto 275/50x15" 26" tall,  rated @ Y 186mpn+ @ $164 delivered.

Hi guys,

I've been reading this topic for several years and now it is the time of my project to decide on my wheels size. The wheels will be the US Mags INDY CONCAVE - U533.

My car is a challenger 74 Hotchkis TVS system, doc diff spring relocation and stock rear end.The sizes I was thinking is front 255/60/15 and 295/60/16  with BFG TAs, wheels 8 and 9 inches.

I have no idea about the back space/offset but I want the fender to look filled with the tire. The car is lowered due to the Hotchkis setup.

I actually measure the rear and attached a picture with the dimensions and space available.

Please let me know your opnions.

Thanks

So on a stock cuda e-body rear end and springs what the max backspacing that can be used without rubbing? 4.5?
Title: Re: E-Body Tire Combos
Post by: Aracer on October 11, 2018 - 04:43:07 pm
On the rear, you can always add a 1/4"- 1/2" spacer to adjust the tire to spring to fender spacing. It depends on the tire side widths.
And math.

Messing around in the shop, I was able to put 315's on the rear and 275's in the front of my challenger!  Looks great to me.  It does have a b-body Dana so there was about an inch more space on each side of the rear.  Fronts fit great.  Don't know the specs on the offset (just had them in my shop), but they are 17" wheels.
